I don't believe Clave ever made the claim but rather a US dealer ( perhaps so impressed after using the eyepieces). As I said I have NOT been disappointed and quite impressed in fact when I first got them and now 30 years later. They go very deep are very sharp, are par focal are lightweight and are a joy to use.
And to the original post; yes having parfocal eyepieces is very handy but over time you will accumulate an assortment and they won't all be parfocal so it's the focuser that has to be correctly positioned and have enough range.
