Why? How? She cant see the outline of the horse from on top of it. You cant see if the horse is on the bit from on top of it. Most people cant tell if their horse is behind the bit from on top.

And I stand by the fact that headset has very little to do with being on the bit.

That may be but is there something wrong with being able to look at a horse and know if he is on or off the bit or has proper headset? He isnt asking her to tell from the saddle he just wanted her to look at some pictures and see some of the differences. So that she can have a better understanding of what he is asking of her.
