Why `Mobile Chrome` as a new browser name?

This is more of a question. The CHANGELOG mentions that v2 now distinguishes between Chrome Mobile and (regular? presumably desktop?) Chrome, and also Safari.

I wanted to ask why? If someone is looking specifically for Chrome Mobile, couldn't they just check both device.type and browser.name? This change doesn't make sense to me at first glance. It also creates problems like this one. What was the rationale behind it, if I may ask?

Thanks in advance.
