One of the limitations of that wiring is that with both pots, both tone controls will work equally on both pickups, and both tones together actually work at a lower frequency than both singularly.
When the volume is down on a pickup, the other tone has progressively less involvement in the other pickup, but it will always have some while there is some volume in that pickup.
No way round that without going active. I assume that is why fender changed the wiring shortly afterwards, because its operation was hard to predict.

Thanks! That explains it
