Quick question regarding Ozma.

On regular Ozma back in "Wiping City" every run i've been in has always had people taking the meteors to the left.
But here i'm hearing they should be taken to the right.

Is there any particular reason for the difference i haven't noticed, or is it just one of those arbitrary "We are gonna do it differently this time" things that just sort of stuck because that's how the world first did it?
