Would love to know what he believes separates his management style from that of a micromanager. Asked directly, I don't think he'd have an answer.
A high performance manager would be sitting in on that interview, too. I bet he's got more important things to do.
I suspect this is some kind of ploy to filter out people who can detect he's a dickhead.
Also, you'd have two people to report to? Does not sound fun.
