I believe that’s correct. This allows the astronauts to adjust to the pressure changes (they operate far, far below 1 atm) as well as abort if anything goes wrong with the suits. This is the first test of these suits after all.

It makes sense that the astronauts would need time to adapt to the pressure difference, but...

This is the first test of these suits after all.

Surely they've been tested on earth before launch???

Yes, but the microgravity plus radiation environment makes for a fundamentally different thing than testing in a lab!
