Actually with further digging things are kinda working correctly as is but the issue comes about not from the LTI auth_remote_username username but from the fact that it tries to 'guess' what the parent auth's auth_remote_username remotename should be on user creation.
So as long as LMS username is the same username as the one SAML send to Mahara things will work as expected -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.
