You need 2 -4 good walk and/or run sessions with GPS on to calibrate to your stride. This greatly improves accuracy. After that the uses of GPS for a session mostly depend on wanting to map your route (Walk/Run/Bike).
Some like to walk, run or bike without their phone.
If you calibrate for stride and want to ignore GPS on Band 2 after that it won't hurt anything.
When it comes to sync, you sync from Band 2 to supplement the data set on your phone.
