If I remember correctly from that live it was mentioned that water does flow differently in one of those. That doesn't make it useless at all but it is not a 1 on 1 match either.
Not an expert by any means but here's my take: Water in the ocean is probably more of a circular / up down motion. Whereas on a flowing wave the water is constantly moving past. You can see it when you look at videos of people surfing those waves. To me the top turns look less flowy. They sort of have to cut the turn short to avoid coming off the back.
Anyways: give it a go! No harm in trying.
