In a way, I agree. On the other hand, sensei first, last name after to me sounds a lot more odd.
Actually, I know of one Japanese teacher whom people call first name sensei. He is the son of a teacher, so just last name sensei would call confusion. Not sure if they do this in his home dojo in Japan also, though.
