$names = 'Fred Flintstone and Wilma Flintstone';

if ($names =~ m/(?<last_name>\w+) and \w+ \g{last_name}/)

I get the result "Flintstone". I don't understand, in the if statement, "if ($names =~ m/(?<last_name>\w+) and \w+ \g{last_name}/)" that how does it automatically match the last name, it should've matched the whole thing before "and" i.e "Fred Flintstone". Also, even when I put the * sign it still matches only "Flintstone".
