Ah, I think I get it now: what confuses you is the opening
of a GUI like file dialog?

If I got you right this time, the best answer is in the
source code:

`find-file' calls `find-file-read-args' to to ask the user which
file name (s)he wants. This one calls `read-file-name', which has
a pretty extensive documentation string. I insert the relevant
part here:

    If this command was invoked with the mouse, use a graphical file
    dialog if ‘use-dialog-box’ is non-nil, and the window system or X
    toolkit in use provides a file dialog box, and DIR is not a
    remote file.  For graphical file dialogs, any of the special values
    of MUSTMATCH ‘confirm’ and ‘confirm-after-completion’ are
    treated as equivalent to nil.  Some graphical file dialogs respect
    a MUSTMATCH value of t, and some do not (or it only has a cosmetic
    effect, and does not actually prevent the user from entering a
    non-existent file).

So this is the mechanism which adapts to how the user invoked `find-file':
if the user used keys, then the question appears in the minibuffer, but
if the user clicked on a menu, (s)he gets a GUI-like file browser (to
me that makes a lot of sense).

I hope I've understood your question better now.

Cheers
