Absolutely, does make sense and is reality. If someone sets up camp, has a picnic and doesn't move, then the gap is important. If they just didn't notice the line moving and what seems like hours, but, is actually only seconds they notice and move then you have lost absolutely nothing. Like they said you are ending up in exactly the same place you would have been if they had not paused. Usually, as the line gets closer to load, there is almost no pausing by anyone, because they are getting ready to have their turn. It gets annoying only if there is a large possibility of line cutters taking up that space and that is what angers people, however, that is not usually what will happen. You will just be delayed for a few moments and then catch right back up. That was much more of a problem back before FP when there was very few times when the line stopped long enough to distract people. We all just kept moving and if someone stopped to pick their nose, everyone behind then had to stop as well. (See
