I have worked on that throw with the Aikido folks here. (sorry they are not NGA...) You are right... it is similar. Too similar for my taste

its just close enough, that it makes it hard for me to do, as I keep reverting to our version when trying to do theirs.
Ours is more diagonal and over the shoulder... that throw (at least according to the Aikido folks I train with) is more straight over the waist. To accomplish that, I turn in more and tighter... where they turn in less, but extend uke in a totally "different" direction for the load. But, it does feel surprisingly similar.
