Because tablespaces behave like humans ;) They gain weight easily, but they only loose it with hard work and exercise...

Seriously: Oracle has never deallocated space automatically. This is obvious as both allocations and de-allocations are costly operations. Oracle doesn't have the 'jo-jo effect' observed in persons who try to slim down.
You would need to resize the tablespace yourself. Preferably before Christmas ;)
