Maybe because SawStop felt that the possibility of a single-point failure
in the safety mechanism necessitated having a bit of redundancy?  This way,
if the arbor-drop mechanism malfunctions you still don't lose body parts.

Also, there's something about dropping a saw arbor while it's still
spinning and producing torque that would probably concern the engineers who
designed it in the first place.
