I think so, yes.

No, the override-action is so the user can dynamically override even his
own settings.  E.g. C-x 5 b should override a user's own settings of
"same-window" for that buffer (after all, that's why he used C-x
5 b rather than C-x b).

So it's meant to be let-bound or set temporarily (the "set temporarily"
is for the case where we implement a new (prefix) command to bind to
keys like C-x 5 or C-x 4).
