In my opinion, the description of that feature should not be part of the
mark-sexp command documentation, because the feature is actually
provided by C-x C-x (exchange-point-and-mark).  The Emacs manual in
section 12.1 Setting the Mark describes this use case well, I think:

‘C-x C-x’ is useful when you are
satisfied with the position of point but want to move the other end of
the region (where the mark is).
