I have suggested a reason once before, but got shot down.
To reduce the chances of a listening enemy overhearing flight commands,
there may have been frequency changes at scheduled times or places, like
this:

The flight starts out with all planes listening for instructions on one of
the frequencies of the flight leader. At a certain time or at a certain
waypoint, all planes except the flight leader tune their receivers to
another of his frequencies for instructions. At another time or waypoint,
another of his frequencies. He keeps his receiver on the original frequency
so he can hear their acknowledgements.

I got shot down by those who said that tactic was never employed, but that
isn't the point. The development of the radio system may have proceeded
along that line on the basis that it might be implemented.
