I think you are confusing two points. Indeed the many computations
emerges right at the start from the AR part of comp.
Then a unique physical mutiverse appears from the UD reasoning.
But then, from the movie-graph or from Maudlin's Olympia argument, a
possibility remains that a "real physical" mutltiverse emerges (real in
the putative Aristotelian-Jones sense!).
But as I said, this moves does not succeed in justifying the "real"
part of it (good because that notion of "realness" is quite vague to
say the least).
We can come back on this latter, in some "movie-graph" posts, perhaps.

This depends entirely of what you mean by physical. If
"physical-supervenience" alludes to the comp-physics, then ok. If this
alludes to physics as understood by a aristotelian-matter physicist,
then physical supervenience need it.
Maudlin talk only about supervenience. For him it is just obvious that
comp makes it physical. Of course he is wrong there (or UDA contains an
error, but this remains to be shown).
I have coined the term "physical supervenience", with "physical" having
its standard aristotelian sense just to distinguish it with the
comp-supervenience idea that mind relies on the immaterial computations
(an infinity of them to be precise).
