Chuck,
Your concern is a real one. Since their board is of a compound radius, they must use a press caul that has a radius no greater than the smaller end (nut end) and possibly a flexible shoe that bends to accomodate any radius between the minimum and maximum. As stainless steel wire has more spring to it, the frets at the flatter heel end are relying on the backfill of whatever glue they'll use to keep them from springing out in time. But the risk would be in the center, rather than the ends.
With constant radius boards as I use, this isn't a concern as I prebend to the exact radius of the board minus about 5.-1" for end hold down. I haven't had any issues to date.
