Azimuth question

I was recently checking the azimuth setting on my cartridge with a test record in which track 2 should be left channel only and track 3 is right channel only. Well, I was trying to listen to each channel to see if I can hear any crosstalk and then I realized that my new VAC Sigma has 2 bias lights that light up for each channel when music is being played.

My question is,if I did not see any light on the right channel lights when playing track 2'of the test record and no light,on the left channel lights when playing track 3, can I conclude that my azimuth is properly set or is this just a very blunt indicator of crosstalk?
