My best guesses
1. If your ball interferes with another player's ball you wouldn't be taking relief, you be marking and lifting to give him relief, and then in that case you would have to mark so that you could replace your ball. But there is one really good reason for marking your ball before you lift it when you are taking relief, and it can be necessary whether you are getting free relief or taking a penalty drop. Still looking for that one.
2. I was looking for some possible consequences of lifting your ball prematurely when taking free relief, not just the situation.
