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.

Okay.
The aircraft has an explosive decompression event at 35,000 feet.
The crew immediately initiate a high speed descent to 12.000 feet
And all in about 3 minutes.

That 23,000 feet pressure difference is less than sea level to the 30
feet underwater level.
A diver can spent 30 minutes at 30 feet with no decompression
required.
In other words he can return from 28-30 psi to 14.7 psi (or 1
atmosphere) without harm in around 2 minutes

I would expect that it is not the addititve difference but the
multiplicative quotient in pressure, that dictates whether nitrogen might
resolve from the blood (resp. potential bubbles). Although I'm not a medical
expert, I do remember that diving in lakes at higher altitudes requires much
more adjustment of allowable ground times than a difference of e.g. 200mbar
at 6000ft would warrant.

Going from a cabin pressure of 800mbar/12psi to an ambient pressure at
36000ft of 250mbar/4psi represents a reduction in pressure of factor 3, more
like a return from 60ft underwater to the surface, which certainly can
create harm, if too much time was spent at depth. Mind you, the people
aboard a plane have spent much more than 30 Minutes at the higher pressure,
probably all of their life so far.
