If changing a display group, do I need to remove sprite from first group?

When I'm changing the display group that a sprite is a part of, it *appears* that I don't need to manually remove it from its existing group first.  However, I thought I'd go ahead and check that's the case and that I won't be setting myself up for weird glitches.

It will remove itself from the old Group first automatically.

Thanks, rich.
