It did, I watched it explicitly for this reason, but I guess unless it's documented somewhere, oh well. It was even googlemail.com for awhile.
Edit: It's possible my concern was the subdomain and my memory is off. It moved from a subdomain to a /gmail at one point (or something similar). That is when I swore off it.
What clearly recall is that there was something wrong, either it was how it did a redirect to google.com first and then back or shared cookies in a very sneaky way that alerted me. (I was building sites at the time and I was privacy conscience early on in my career)
