Feedburner treat gmail two different account, or?

Hi, everyone, I ve just set up my blog and wanna increase the number of my rss subscription. So I used gmail acount generator registrating a number of gmail account first, then manually subscribe my blog using each gmail account.

And I found you can send two subscription letter to one gmail account, I mean it seems Feedburner treat [email protected] and [email protected] different. Someone handled that? If so, one gmail account equals four feedburner subscription, two email subscrib, one google reader subscrib and one google desktop subscrib, just found that and post here, have a nice day everyone!
