That's interesting. I'm not sure how common it is but I sign in all the time by doing just that. I just always try to use sites immediately because they usually cause signing in (or up) to be part of the flow.

For example, I go to my bank website and click "My Account" cause that's what I want to do. It asks me to sign in, and then redirects me to my account page. I don't click sign in.

I'm not saying this makes it ok. This just made me aware of my technique for the first time and I thought it was interesting.
