"Issued to" and "Domain Name" doesn't match but still valid and accepted by all major browsers without any warning.

While previewing my blog post in Blogger, I noticed that my blog was previewed via SSL. When I checked the certificate information, I noticed that "Issued To" and "Domain Name" didn't match. Here's a screenshot.

Blogger SSL Certificate

Domain name was techronak.blogspot.com but SSL certificate was issued to *.googleusercontent.com and the best thing was my browser (Chromium) didn't issue any kind of SSL warning.

How does this kind of SSL Certificates work?
