I contacted SawStop a couple of days ago to learn if the SawStop would
work on a spinning blade if all power was lost. The answer is that it
would for a second or two until the residual power was absorbed. After
that if the blade that is cutting wood is still spinning you would be
unprotected.

What does "residual power was absorbed" mean?

Not sure... ;~) Here is what Saw Stop indicated,

the cartridge might stay powered for about 1-2 seconds at most
while its internal voltage falls off

Sounds like they have a couple of filter caps that will carry the
mechanism for a (very) short time. Typical marketeering.
