Does it work for /user or /user/register?

I tried to install the module, but found that it does not work for example.com/user or /user/register.

I turn off the login block.

Before login, if /user, /user/register is https redirected, nothing happens after the login or register button is clicked. apparently user_login_validation() etc. functions are not called at all. If /user is NOT https redirected, login process goes properly.

At first, I suspected that /user and /user/register have forms built in and that is the reason the module doesn't work. My site only has /user form https-redirected before login. However, after login (with NO https redirection for user/*), all pages that are https redirected and have forms built in work just fine.

So I suspect the module may only not work for /user or /user/*?
