Good one! lol
Yesterday, I was going to ask about whether the leading outer spiral arms would persist now that they are well formed, but I got the answer from the link in your last post, Dennis.

The leading arms may be allowed to persist because NGC 4622 is dark halo dominated (i.e., not "maximum disk" in the inner regions) and displays a significantly rising rotation curve.
