Where "doesn't work" means "doesn't downcase but keeps HELLO", right?
Have a look at (info "(emacs) Replacement and Lax Matches") which
explains it. I think the default `case-replace' value of t is the
problem here.
That said, `case-replace' is actually a nice feature. It's just that
with an explicit `downcase' it's very counter-intuitive. I'd suggest to
report that as a bug.
What you can do is instead of saying 'y' when asked to replace the
current occurrence do 'E RET' instead.

I don't understand what you mean here. When I change the = in the
replacement to, say, the letter t, HELLO= gets replaced with HELLOT
which is the same behavior as above...
