They stall at significantly less than that when you're running them off of a real battery whose effective voltage drops significantly when you start drawing lots of current from it.

It's the same reason that you can stall them at all in the first place; if you naively just calculate from the stated stall torque of the motor you'll find that your robot would have to weigh an ungodly amount to stall them at any gearing you'd see on an FRC bot.
