Yes I can confirm this. Only noticed it twice, once with X3c and once with X3d. Not sure if it is intermittent or I just don't always look or notice.
Example - A couple of days ago I recorded a track, then did a drag move that I wanted to undo. Usually I just hit CTRL-Z, but for some reason I went under the undo history and it said "undo recording." I clicked it, and it undid the drag move. So it seems like just the label is incorrect.
