Are there two areas where a user can log in on a WordPress blog?

I have modified my theme. I have added a button to the comments.php so that when the user wants to add a comment and he is required to register or log in, he is given the option to click on a button (It is part of my design and requirements for my specific web design).

Here is my question. Are there, in fact, two areas where a user can log in?

I noticed that if a user clicks on “log in” from the home page, he goes to a page that looks something like this:

But if he clicks to respond to a blog, he goes to the bottom of the blog like so:

One of the places can be modified by the comments.php page, the other is the WordPress login page and that can be customized by using CSS and adding a reference to the functions.php file.

As far as the database is concerned, what is the difference between signing up to post a comment and registering to login from the wordpress login screen? Are the same entries made in the database when someone officially registers on a blog as when someone responds to a blog and does a pseudo-registration?

Also, how is the css file configured to represent the WordPress login screen? Does using a CSS file replace the login page or does the CSS file add content?
