I think you should have kept the po changes in the logical tag, and dropped them later on when applying on top of debian/new.
Logical should show what the delta is at that version, and it does have the po changes (which I also think were added by mistake). But they should be dropped at rebase on top of new/debian time, not in logical.
I would add a "[previously undocumented]" line to the commit that you split out about the pos, and then drop it when rebasing on new/debian, possibly with a comment ("* Dropped: previously added PO update, apparently by mistake"). You could also ping Marc to see if he remember what that was about.
