C-x C-e itself might overwrite the match data while looking at the
buffer to decide what to evaluate.  And after running that command, tons
of other code is run, such as post-command-hook, process-filters,
timers, pre-redisplay-function and whatnot, all of which will gladly
overwrite the match-data.
