This is not to crit chain, it's because if 2 spells hit sufficiently close to each then if first one crits and 2nd doesn't then you don't lose the heating up.
The thing with the afomentioned is however that it works because fireball and pyro hit at the same time, but with scorch it would not, so you don't exactly replace fireball with scorch, cause then you lose out on that crit if pyro doesn't crit.
What you do instead is that you know scorch always crits, so you do scorch > Fireblast > Pyro and then if it doesn't crit you do the same again, but if it crits you just do Scorch > Pyroblast, and then same again depending on pyro crit or not.

Hope that cleared up any questions.
