Hello Larry and welcome to the Cow Audio Forum.
Mastering is more about final EQ, compression, limiting and level adjustments. You appear to be asking about panning.
I don’t think there’s anything carved in stone about panning preferences. I try to avoid severe, full left and full right panning unless there’s a good reason to do so.
I tend to be conservative in situations like this and keep the speaker’s voices more to center, if not “mono” or with both tracks panned to the center because, sometimes, somewhere downstream, someone will incorrectly decide to use only one channel of my two channel audio.
