As I looked at it last night, it reminded me of the first EVA (”spacewalk”) done by the Soviets.
It turned out that the Soviets didn’t have a rigid suit, and as the cosmonaut tried to reentry the capsule, the suit had ballooned out, making it impossible to fit through the door.
And, IIRC, the Soviets were still using 15 psi pressurization at the time, too.
He had to deflate the suit to a dangerous level to get back in.
OTOH, not deflating it wasn’t an appealing alternative.
