Oh, it should be safe - those are completely unused. It comes from various cut content from Gahreesen, unrelated to the Wall.
For the record, ReadyIdle and ReadyJump seem to be animations for jumping between the rotating bridges. LandingRoll was supposed to be played if you jumped off the big gear while it was rotating in the Well's power room. ClimbUpDebris and DescendDebris are used as transitions between the first and second floor in the Well, as seen in this video (in which you can also see there was a big mirror in Sharper's office at some point).
The Wall has its own set of unused animations, but might as well leave those here for now...
