All the game does is switch the forms, but fails to deequip Older Rydia's incompatible equipment.
Somehow, I'm not surprised by this. You'd think that she would be unequiped, since logic says it.
However, I don't see that as an ill side effect since the options for Younger Rydia still suck.
Given where her line stops, this is actually very beneficial, since she'd probably get slaughtered without the good gear. Although, if you tried to swap equipment during the trial, then things can get really hairy.
