After you apply an envelope to a track, it means you can no longer adjust the control for the track because the envelope will change it during playback. Basically, Offset mode allows you to adjust the entire envelope (by adjust the control) without having to go through and edit every node.
For example, if you add a volume envelope to a track and then you later want to adjust the volume control for that track, you would switch to Offset mode, to adjust the volume control. This would adjust the overall value of the envelope and keep the node changes intact.
