Not quite.
* USB 3.0 specifies SuperSpeed. No need to go on about GenX given it's the first one introduced by USB3 is there?
* USB 3.1 specifies two data transfer modes: Gen1 (the one introduced in USB 3.0) and Gen2 (the fancy new mode just introduced).
* USB 3.2 specifies the Gen1 and Gen2 modes from USB3.1, and adds two additional modes.

USB 3.0 also specifies lower speeds. They didn't need to use "Gen" then, and nothing changed to make them need it after.
Nobody cares if multiple speeds are "introduced by USB3". If 3.0 introduces one speed, and 3.1 introduces a different speed, people can understand that just fine.
Even if you do want to focus on "introduced by USB3", then you just need "3.[generation]" or "3 Gen [generation]". Not "3.[spec revision] Gen [generation]"

This is supposedly better than USB 3.0 (original standard), USB 3.1 (new standard, same SuperSpeed as USB 3.0), and USB 3.2 (new standard and also SuperSpeed+).
