Pretty clearly because they were defecting to an opposing monarch. It wasn't reconciliation that had her open fire by itself, she only gives the order to shoot once she's told that Calia is on the field. In any case though, this goes into a broader problem with this abhorrent novel and that's that it frames the separation between undead and living as being a minor misunderstanding that flawless paragons of light and morality like Calia and Anduin can easily resolve provided that the bad guy causing it, Sylvanas, is done away with.
This is emphatically not the case throughout the entire rest of the lore prior to the book. The Forsaken were not rejected because of Sylvanas, but firstly because they were undead, meaning they were abominations against their prevailing religion, secondly because their positive emotions and so forth were suppressed, making them hostile to one another and incapable of coexisting and finally due to the historical considerations that the undead had just destroyed tons of human kingdoms. It was a mutually hostile affair.
The Forsaken were not sadsacks that were yearning for a hug from a living human else they'd wither away into irrelevance, with Sylvanas abusing this. They were themselves a cruel, hardened people, who accepted some aspects of their prior lives - Lordaeron, natch, which Sylvanas never dismissed nor had any motive to as it was patriotic fervor that drove the Forsaken throughout the entirety of Cataclysm and that even gets brought up by the refugees in Orgrimmar now, but dismissed others, such as reconciliation with the living. This is because the living wanted to kill them and had a kill policy long before Sylvanas attacked Gilneas.
They were not wrong to do so, they were well-motivated in this, as the Forsaken were well-motivated to not want to be killed. But what it wasn't was a black and white affair where Anduin and humanity were paragons of goodness who could easily overcome their problems, Sylvanas was pure evil and the Forsaken were irredeemable sheep who just wanted to be buddies. It's an infantile story that ignores all prior history of the races, where if anything their membership of the Horde and constant atrocities would be grounds to hate the Forsaken more, not less, done solely to beef up one character at the expense of another, the overarching identity of the Forsaken be damned.
Her goal, spoiler alert, is to kill everyone in her capacity as an Old God puppet. Beyond running in contradiction to years of portrayal, it's that it runs counter to her current portrayal and the internal monologue which has zero mentions of this whatseover, has the Horde keep existing in her victory scenario and doesn't even show her as particularly enthusiastic about starting a war. She doesn't spare Baine or let him release Derek because it's part of some cunning plan, but because the loyalist route was a last minute addition to tide over players who recognized the same thing I'm talking about at the moment. It's not an intended element of the story. Sylvanas doesn't release Baine because there's some plan, the story is clearly that she planned to kill him, itself if successful the greatest favour she could do the Horde long-term and easily making her among the top three Warchiefs, but is foiled by the rebels and the Alliance working together to stop her.
Because of these alterations out of fan outcry, these elements of her behaviour make no sense, as they were never intended. Concurrently, the whole Derek plan needs to be gone through extensive mental gymnastics to make work and itself opens chasms worth of plot holes, such as why she doesn't just make him a mindslave if she has no issues with this, why all other undead have free will and go on to betray her and so forth. It is done because it's not really a character scene for Sylvanas, as she's irrelevant in her own villain-batting expansion, it's meant to set up the nu-Forsaken and to give Baine something to rebel over because they didn't fully realize what they'd done with Teldrassil until much later and how it looked for literally zero people in the Horde save Saurfang to give the least bit of a fuck.
