Actually when doing any sawing on a table saw you should have a riving knife installed, not just for resawing. I have seen and had it happen if doing any crosscutting or rip cutting releases tension on the wood fibers and have had boards bow and twist while cutting and pinch the blade.
A youtuber named Make something showed this on a project he ripped a board on his table saw and it bowed pinching the blade, even showed it in slow motion, luckly it didn't kickback.
