Indeed, it's not 100% equivalent. My experience is that in practice, in
98% of the cases, you can replace the first with the second, as for the
remaining 2% it's probably equally split between cases where it would
introduce a bug and cases where it makes an existing bug a bit more obvious
to the programmer. This last case is when people do for example:
(save-excursion
(set-buffer foo)
(re-search-forward "bar")
(match-string 1))
where they should have done
(with-current-buffer foo
(save-excursion
(re-search-forward "bar")
(match-string 1)))
