//m changes the meaning of ^ and $ and there aren't any of those there, so it isn't needed. //m doesn't do anything else. And using \1 on the right side of a subst isn't actually a backreference and doesn't make anything harder to debug, it's just deprecated syntax.
The use of \1 is a sign that the poster forgot to enable warnings, though.
