Yes, that is the concise explanation. And, as Marshall says, it's probably better that way. It certainly makes my current project easier if that is so.

It appears the obverse of u :. v is v :. u and not simply v .  This explains

My inclination is that it is correct in enforcing that the obverse of
the obverse is the original function. I'm open to good reasons why this
isn't always the case, but I think if you need to break this rule, then
what you're looking for probably isn't the obverse. Using &. in this
case will just complicate the code.

Yes, that seems wrong.  It should be

i. :.+

shouldn't it?

The obverse of i. :. (i. :. +) should be (i. :. +), and
the obverse of that should be + .  I think.  But it isn't.
