Flyback SMPS leakage inductor reset voltage?

Hello,
Please can you confirm that when the primary FET switches off, the voltage across the leakage inductor, which resets the leakage inductor, is the (RCD clamp voltage) minus the (Voltage referred from secondary to primary)?

....and if these two voltages were equal then there would be no voltage to reset the leakage inductor and that would be a big problem.

Hi

Could you provide a schematic of your flyback as the explanation is a little bit confusing?
