It's not the benefit of trapping air inside the waders to aid in floatation, it's denying water ingress, which quickly lowers body temperature and makes getting out of the water all that much more strenuous and demanding due to the extra weight of the entrapped water. I've "stepped-off" into deep water in breathables and standard waders, but never neopenes. The first thing that you have to due when exiting the water is to crawl out prone and the get you feet up in the air to drain the waders prior standing. Getting back into a boat, even with help from fellow crew members is quite challenging in warm water...even more so in frigid water conditions.
Yes, these examples emphasize the utility of a float coat over top of waders. With a zipped up float coat, you can fall in or overboard and not be saturated for quite some time. I'd encourage everyone to try it, you don't even submerge.
