It's hard to answer without knowing what "this" is.  If you mean code
that first moves point in an undisplayed buffer and then switches to
that buffer in the selected window expecting to see point in the
location to which it was moved, then no, you cannot expect this to
work reliably.  (Previously, this would AFAIR luckily work only if you
didn't have the same buffer shown in any other window.)

I think the solution you suggest there is the right one, it should
have been taken long ago.
