Yes.  (Which is why the Subject line says "doc string of...".)

Yes, thank you.  That was the point.

A doc string that says that `grow-only' makes the "windows go back to their
normal size" is 100% wrong.

AFAIK, `grow-only' never returns minibuffer windows to their normal size during
a given invocation (reading of input).

The best that could be said is that "until their display becomes empty" is
unclear, and that something was meant other than the minibuffer being emptied
during its current invocation (input reading).
