current_source_alias is exactly this - the alias of a certain $rs object.
When will it not be 'me'? Simple:

my $artists_with_cds =
  $s->resultset('CD')->search_related ('artist', {}, { distinct => 1});

Now the alias of $artists_with_cds is not 'me' anymore. It's 'artist'.

'alias' is a valid *undocumented* (thus internal) attribute (as many many
others), and you should not be messing with it.
