Most executions have a "point of no return" segment that once reached it won't matter if the execution is finished or not. Usually is a pint where the regen happens. Typically any decapitate or finishing slash/stab.
Videos would help better though.
It's hard to reproduce by myself. but I assure this happens even when the shaman is interrupted at the very beginning of the execution startup. Not sure if this applies to all executions though.

If I'd the brushing then that's why. You haven't actually executed them. Their allies have until a certain punt in the attack to stop the execution, these times vary from execution to execution.
