The profiler doesn't seem to take HTTP redirects into consideration, incorrectly reporting the web host and SSL details for Vidyard, though I'm sure for a few others too.
You're correct, currently the "Web Host" is determined solely by what shows up in the A records for the domain.
I've been working on updating the profile to determine the host based on where the HTML is ultimately served from, along with some pretty substantial changes in host detection heuristics. These are non-trivial changes. I was hoping to have them done in time for this report, but tradition dictated that I produce this report now.
