Note that your explanation is completely different
from the Perl 5 semantics, which my impression was
that the same model is followed by Perl 6. To wit:
# Perl 5 code
my ($x, $y); $x = \$y; $y = \$x; print $$$$$$$$$$$x;
If the reference semantics changed drastically, please
reflect it prominiently in the relevant Synopsis. :)
