Yes.
The submission clearly says microsoft.com, not research.microsoft.com
Didn't you know that HN shows the research subdomain in submission titles?
EDIT: Sorry, this reply sounds a bit snarky.
EDIT2: I'm wrong! Thanks to TeMPOraL for pointing out my error about HNSearch and HN.
'HN to show subdomains' is, I think, number 1 requested feature, but it never was officially done. Is there a whitelist of domains somewhere that get their subdomains shown?
EDIT
Except it doesn't.

Make sure to remember that a) lots of HN plugins fix that, and b) hnsearch is NOT HN, even though it looks similar.
Oops. I didn't. Is there somewhere a written collection of rules to learn?
It's an annoying bug, it keeps getting raised as a problem, but it's never been dealt with.
