Gaits That No Other Horse Does?

A quote from National Geographic, about the Icelandic Horse:

"...the Icelandic horse does two gaits (besides walk, trot, and gallop) that no other horse does."

Is this true?

There are many gaited horse breeds that do intermediate gaits such as running walk, fox trot, stepping pace, saddle rack, and rack (tolt), as well as pace.

Forced Frame to Tolt

Is the tolt natural to the Icelandic Horse?

If so, why does the horse have to be put into an unnatural forced frame to gait?

Why hurt the horse to gait?
