This certainly seems like a bug to me.  At least I can't think of any
reason why it would be the case.

IMO .SECONDARY has always been iffy.  The way it works and the side-
effects it has are odd; in my opinion it shouldn't exist in the first
place.  I'd have to examine exactly why it has this behavior before I
can say whether it really has any value or is a pure bug.
