But there's also a bit even more than that. Thros is kind of an intersection of cosmic powers. It exists as a physical location on Azeroth (or at least the entrance does), is part of the Emerald Dream, but has a path to the Shadowlands into it.
So like, yes. The Emerald Dream IS an ordered part of the realm of life, but I think that there is an active distinction between even an unaltered Emerald Dream and the Lifelands.
If I had to guess, The Emerald Dream (in any form) is akin to the Lifelands the same way that Death Knights on Azeroth travel in a realm of death they call the Shadowlands, but isn't exactly THE Shadowlands.
