Where did he mention divers and hyperbaric situations?

He claimed a rare complication.
That is the only situation imo.

You're wrong. It can happen in any decompression situation, if the
decompression is severe enough. Like e.g. in a pressurized airplane at
very high altitude which instantly looses its pressurisation.

For some-one to have 'bubbles' develop in the CNS (or anywhere else)
in an aircraft decompression you would have to had been in a
compressed state before emplaning.

You're wrong again.

Mixedup is not correct.
he has never been correct on any point he has ever raised

And again you're wrong. You may or may not like him, but sometimes even
he is correct. But then, this is probably a tad too grey for your black
and white world.
