1995 Dodge Neon oil leak

Engine Mechanical problem
1995 Dodge Neon Automatic 250000 miles

I have a 1995 dodge neon and recently I had two seals blow out behind the timing belt, as told by a mechanic when he diagnosed my car problem aka my oil leak. He told me that before removing anything at all that my timing belt was most likely soaked with oil. He suggested me getting a new timing belt even though it was replaced in spring. How does he know the timing belt will be soaked and should I get it replaced? I don't have the money at the time so I decided I would take my chances and just ask him to clean it up as much as possible. Was it the right choice?
