I understand that it affects resizing (by changing which other window
is resized as side effect of changing the size of the window we want
to resize), and deleting (by controlling which window will be given
the space released by the deleted one).  But what is modified in the
behavior of splitting?

What I mean is that the user have no way of resizing the internal
windows, only the live windows, AFAIK.

A Lisp program can resize an internal window, but doing so is
precisely equivalent to resizing one of the live windows on the same
frame (again, AFAIK).

When you talk about resizing a live window, I understand exactly what
is meant.  If by "vertical combination" you mean the internal window
that is the parent of 2 or more live windows, I can understand that as
well, assuming that you are talking about a Lisp program.

If you mean anything else, please explain what I am missing.

Some of these are unavailable to users.  We were talking about a user
option.
