The relevant portion from the manpage says:

     ....... If  (and only if) the input symbol is the only thing
     inside the  conditional  of  a  while  loop,  the  value  is
     automatically assigned to the variable "$_".  ..............

Doesn't say anything about the conditional of an "if".
In fact, early releases wouldn't let you say:

	print while <>;

Instead, you had to say:

	print while $_ = <>;

print "$ARGV[push(@ARGV,'Just another Perl hacker,')]"
