Coil over conversion for stock k member/steering

I was checking out the GTS catalog to see about this new system and on the first web page they state:

"Unlike some competitors, the GTS K frames use a built in upper coil over mounting point instead of using
the factory weak shock mount. Factory shock mounts were never designed to take the weight of the vehicle
and the movement of the suspension. Even braced or supported, this is one area GTS felt should not be trusted
and developed the stand alone coil mounts for our kits."

So what's with the hoop style upper shock mounts if, as they state, they can't be trusted?
