Good catch! The same symptoms can be seen in cperl-mode.
Both perl-mode and cperl-mode treat "$" as quoting character in their
syntax tables. This is needed for Perl's punctuation variables like $(
and $" which would otherwise be interpreted as unbalanced parens or
quotes.
In a string, this safety belt is not required, and it actually misfires
in the case of "$\"", which is part of the demo code.
This is now treated correctly in the Emacs master branch for both
perl-mode and cperl-mode.
