It actually replaces the leading comma, so if $src contains nick1 you're
going to still have a leading space (now comma) on the string. It also
replaces all occurrences of $src in the string.
If you want it to work 'right' (i.e., snip the trailing comma if it is at
the beginning of the string, and the leading comma if it isn't), then try:
$mystring1 =~ s/(,)?\Q$src\E(,)?/$2?($1||''):''/ge;
