This part happens in the background without user's notice, so this
portion irrelevant.

But this is the portion that requires user interaction, what happens
between the first update notice and the message that all updates were
installed. So from a users POV the time is reduced dramatically. I think
it could even more than halve because scriptlets are only running once
instead of several times.
