Extension tiles are actually added for all tiles with height > 1, but you're correct that the possibility of the height of a tile changing after one has been added to a level has not been considered.
In 1.6.1.2, the game will now ignore superflous extension tiles when loading a level. This means that if you change the height of a tile, just save and load the level again, and there will be no orphaned extension tiles.
When a tile is 3 blocks or taller, placeholder blocks are added. If the height of the tile is decreased the placeholder blocks remain and are impossible to delete. Deleting the placed tile does nothing (since the placeholders don't belong to it anymore).
