Here's a possible example: 

A ProRes QT converted from a Canon XF305 MPEG clip will have two audio tracks, labelled left and right. When imported into an Avid editing platform, only the first track (left) will be "seen" and imported.

If the audio tracks are re-labelled in QTPro as two Mono tracks, the Avid will "see" both tracks and import them both.
