Why would they? One is tuned to 950 KHz, the other to 1320 KHz, a
good part of an octave difference.

This is the same fuzzy logic that says that you can measure the output
Z of an amplifier at one frequency by injecting another signal at a
different frequency.

If it was this easy, the bother of load pull techniques wouldn't have
become popular and the norm.
