I don't see what's more or less complex about it.
With other-frame-window `C-x 4` is a (prefix) command.
So just like `C-h k C-u` gives you help about the `C-u` binding,
`C-h k C-x 4` naturally gives you help about the `C-x 4` binding.

So if you're interested in the `C-f` binding available after you hit
`C-x 4`, it's only natural to use `C-x 4 C-h k C-f` (and not only it's
natural, but it's the only sane option unless we break the `C-h k C-x 4`
case).

You're talking about the current `C-x 4` which is a keymap.
I'm talking about the case when we've change `C-x 4` to be a prefix
command, as provided by other-frame-window.
