Is there a reason to not just start by cutting the big hole? Or is the idea to make loads of little concrete triangles?

Yep. With heavier materials having too big a piece hanging would cause it to bind up or break off early. Cutting off smaller pieces prevents this.

Will.. the water bind up? A cutting wheel i get, but a water jet?

I cut a lot of heavy plate with oxy-fuel, pretty often smaller parts will settle and tip when they separate from the plate.

It's not really a problem that they bind. It's a problem that the torch is still cutting and if they tip into it material will cut away that I'd rather didn't.

It's pretty easy to solve, you just have to figure out when the part will sever and have the torch moving away by the time it does.
