I think that you have not understood the point.
1. All employees having basic pay + DA of Rs.6500/- are covered by the EPF Act.
2. If an old employee, crosses the threshold level of Rs.6500/-, his and his employer's contribution will be restricted to the threshold level of Rs.6500/-.
3. If a new employee with a basic + DA of more than Rs.6500/-, it is not mandatory for him or the employer to subscribe to EPF. However with the approval of the PF Commissioner, he can be enrolled. In this case, the employer's contribution is nil.
4. If an existing EPF Subscriber employee crosses the threshold level of Rs.6500/- he and the employer should continue to pay the contribution restricted to Rs.6500/-, the maximum threshold level.
I trust that this clears your doubts.
