If you look at the full body of his work, this admin truly is trying to follow policy and the customs of Commons and WMF projects in general.
IMO, the policies need to be tweaked so that admins like him will have better policy to work with. And we need a broader group of people commenting in all deletion discussions so that we get a more globally representative view of what is appropriate for Commons to have on site.
One thing Wikimedia as a whole suffers from is no "solidity" when it comes to policy and rules. Everything seems that it can be adapted, broken, changed, manipulated..etc. I think that's a problem.
