Yes this is generally considered normal, provided the movements aren’t bloody or overly painful. The “inactive” portion of colon you have can still produce its own mucus (looks a bit like a pale gel), that can need to be expelled. I also get gas with my ileo - both in the bag and passed normally. Finally there is also the small possibility of some stoma output re-entering the opening into the lower colon (as both ends of the ‘loop” stoma are diverted into your bag). This may end up looking more like a normal bowel movement, but should be modest in quantity.
