Well, here is my try (which does not work!). It is possible to use reverse and then lookahead assertions:

use strict;
use warnings;
# use re 'debug';

my $s = '#@##@###@####@#####@';

my @list = reverse split '@(?=(##)*[^#])', reverse $s;
print scalar reverse $_, "\n" for @list;

I see the regexp only matches at the good @ signs, but I am getting a couple of ## in the output that I can't explain. I have tried with use re 'debug' and so I know the regexp is matching where I intended.

Output:

#@##
##
###@####
##
#####@
