It does compare nothing, it is just assigned to $patternDir.
When used, for instance in
$filename=~/$patternDir/;
it _matches_ if $filename is empty or contains one or more of the
chars a-z, A-Z, 0-9, /, [, ], - .
This includes paths on platforms separating paths with '/'.
See
perldoc perlretut
perldoc perlre
etc.
Maybe you want to clarify your queston.
