That might be a useful thing to do regardless of no-fly times. And
yes, many dive computers seem to consider the two things the same
(sometimes with a "no-fly is desat time with a minimum 24-hour")

I'm not sure what the cut-off for "desaturated" is really considered
to be, considering that I've seen some wild variation in desat times
