Sure, I also believe it is a mix of both. But, this study is probably overestimating the degree to which the legalization is responsible for the change in attitudes. Also, it is probably "only" accelerating a change that was going to happen anyway. For example, there were times and places when divorce was legal, but did not become "accepted" socially for a generation or several. So, I don't think the causation primarily goes from legalization-->social attitudes. But, I agree it's probably a mix.
