I can't explain it but have noticed the same polarity changes during a 
pass. Like S-9 to S-1/nothing switching between polarities with my 
antennas... it's been  handy to actually have the ability to change 
polarities in the past for me. I do not have the ability to polarity 
switch on 2 meters, only 70 cM for the downlink.
