Your question was:
Indeed, so what's the point of doing that?
where AFAIK "that" referred to "defer fontification when input is pending".
And I explained that the point of deferring fontification only when
input is pending (as opposed to doing it all the time, as in the
current jit-lock-defer-time system) is that we defer less often, more
specifically we only defer "when we know for sure that the user is
waiting for further processing".

That's why I said "because almost none of the text had been
fontified earlier". It's not always true, but the end result is the
same: the double redisplay takes extra time. Does it take exactly twice
the time? Maybe not exactly, but I think that a factor of 2 is a good
enough approximation.
