Yes, that seems to solve the mystery.  Thx.
There's no exception for whether BUFFER is in
the selected window.

Whether that behavior makes much sense when the
buffer is in the selected window and the command
is on `C-x 5' is maybe something else.

In any case, the bug is closed.

It was not obvious to me that this is the
intended behavior.

I still don't think it's the best behavior.
IMHO, `C-x 5' should win, and I think users
would generally expect that.  It doesn't.

And that's ultimately documented.  You've dug
down into the labyrinth and found a doc string
that documents the behavior.  Good.

As for things not being obviously the intended
behavior, you yourself wrote:

Please forgive others less intimate with this
code than you.
