That's a different scenario. It sounds like this guy had some time to get
ready and initiate the bailout while his ship was still climbing and under
some control. That's a lot different than having a mid-air at 1,000' AGL.

Absolutely. When he realized he had to jump he was going UP, not
falling down. It was just an example.
Still, I can easily imagine someone having a low - level midair and
then having quite w few minutes to decide whether to jump or not.
One's glider does not have to disintegrate.
