Agreed not "self energizing" which would tend to make one direction superior to the other.

That said, any differences in equalizing between front and rear shoe (and the two do "self equalize as the wedge/cam move between front and back rollers) will be amplified as the brakes are adjusted. If one of these (either wedge or cam) get hung up, the owner may attempt to "adjust" to restore braking - and this will bring one shoe to wear more than the other.

Even this is not a deal killer. Still equal pressure between the shoes.

But, when backing, the entire assembly may move and upset the adjustment to the point of allowing only one shoe contact. (still binding on wedge or cam)

So in theory I agree. Practice may bring in the unexpected and his car may be subject.

I would check the equalization/wedge/cam areas.
