Ability Names that sorta make no sense, and what names do...

Wouldn't Redoublement be more or less correct? Corps-a-Corps starts with the rapier at the center of the body, it's moved to pointing down and right by the end of Zwerchhau, and Redoublement moves it back to the center.

I've only ever seen the term used to describe a return from a displacement caused by the opponent. But I've never seen or heard of someone purposely leaving center line by such a large margin as they'd need to double back, let alone to attempt to cleave someone's thighs with a "foil" (an edge-less, ball-tipped training sword).
