I strongly recommend you read his book, "Hunter Seat Equitation." It's kind of treatise on the subject.
George Morris created the Crest Release for beginner riders, as upnover stated - for riders who cannot support their upper bodies with their lower. Riders who do not have a solid lower leg and solid core to support their upper bodies, need the crest releas to remain solid, functional and supportive while going over the fence - so they do not hinder their horse and get into their horses way.
The Automatic Release, is for riders who CAN support their upper bodies through their lower. Riders who have a solid and functional lower leg and a functional core, can support their upper bodies so that they do not hinder their horse, get into their horses way and can easily follow their horses motion over the fence - because they are solid in the lower extremities.
IF you cannot support your upper body through your lower, then you are not ready to do the automatic release.
The issue GM has, as upnover already stated - is that there are MANY riders who are very capeable of doing the Automoatic Release, who are using the Crest Release as a crutch. It has become such an over used release, used by all levels.
GM will nail any rider who he sees, doing crests when they clearly should be doing the atomatic.
But I stress, you cannot perfect your release, until you have a solid lower leg. That's why, the crest is very benefitial in this matter.
