Role(s) assigned(s) different from the page "user/register"

Hello,

When a guest falls from the page "user/register" it automatically these roles (through the module "Auto assign role"):
- Identified User
- Advanced user

I create an entry for a node with only one role:
- User logged
At the moment when a user is registered from the node, it inherits the standard roles of the page "user/register.

Is it possible to do that? Thank you very much for your help.
