This change was necessary for the index for the swept area in the PhET-iO tree to match up with the index used in the graph. I think the commits were made in #214 but the discussion around reversing the order doesn't appear to have made it onto GitHub.

I'm not thrilled about this change, but there didn't appear to be any other way to get the phetioID to sync up correctly with the view.

@AgustinVallejo please correct me if I'm wrong. Otherwise, this issue can be closed as wont-fix.

You're right, this was decided on, I'm going to close this issue and summarize our slack discussion in the one you linked.
