Au contraire, you can see them moving.
When one is in front moving to the east and another is behind moving to the west and they cross, you can easily watch the distance change.
Some of the moons orbit in less than 2 days (unlike ours which takes a month).
Perhaps you can in those special circumstances, but they don’t come around too often, comparatively speaking.
...and I would imagine that would likely involve very high magnification and a very good scope.
