Note that it makes no statements about other files -- only about the file in
which the "use vars" pragma appears.

No, since the documentation does not claim that "use vars" only takes effect
inside the file. (At least, the bit you quoted does not.)
Remember, "use" is like a require within a BEGIN block and is executed at
compile time. So when you "use test3" ahead of using $x in test.pl, Perl has
already seen the "use vars" declaration for $x.
