Nonsense. The feet are moving exactly the same way. The numbered counts are falling on the beats exactly the same way. They have exactly the same problems phrasing. The only thing that has changed is the numbering used for the beats. BUT as you note, it gets the down beats "right" - they fall consistently in the count, rather than drifting, and as a consequence you get a two beat pulse from the dancers instead of a three beat pulse. When I saw this demonstrated, the effect was remarkable "hey, they aren't dancing waltz any more." Perhaps you could accomplish the same thing by carefully adding dynamic accents when counting the appropriate 2s and 3s instead. Good luck with that. I'm a westie, so I don't care at all about starting on the same foot at the beginning of the musical phrase. In WCS, you generally get better contrast if you align the beginning of a phrase with beat 3 or 5 of a pattern, and those are normally on opposite feet. Having the same count indicate different feet is pretty twisted, and if you want to call that a deal breaker, I don't blame you in the slightest.
