Can someone please explain this?

Can someone please explain exactly what "Enable slide wrap-around" does under the Slide Settings tab of the options menu?  I understand what the resize vs wrap-around does under the Display Settings tab, but I can't figure out what the checkbox under Slide Settings is for.  Does anyone know?

Normally when you get to the last verse of a song and you click the next verse button, nothing will happen. If the slide wrap-around option is enabled, doing this will instead take you back to the first verse.

Useful if you're using the timed slide option, since it will cause the 'song' to loop indefinitely, rather than stopping at the end.
