Hi Bruce, good to read you here. I also think it important for beginners so that they can start building exposure and relationships with people from other styles. So what if they are confused for a couple of classes or days...I was confused all the time when I started, it didn't matter what style.
The point is the attitude change, and the relationships. These two things are seeds that continue to grow throughtout the students tenure in aikido. And I think the fruits are well worth while.
