Well, I'm no idea about this but could it be this way?

There are ~500MB difference between the current status and the
previous snapshot.
So deleting that snapshot and pruning would give you 500MB back I guess.
Bad thing is that when you have a lot of snapshots with the same files
modified, this is near impossible to calculate manually, but there
must be a way of calculating this :-)
