CW translation and CW rotation movements - 4 revolutions
But what's happened if the translation movement is CW and the rotation movement is CCW (backward)?

If small circle is rotating inside a region, its rotation is CCW (backward)
But small circle gain a CW rotation. (black part always touch the "floor")
In other words, we lost 1 CCW revolution.
