What the contractor is doing is done all the time. He can run double joists at each end with a double joist hanger. He can run a double or triple joist 10' in to the center perpendicular off the ledger with double/triple joist hanger out to a girder 12' out running the 20' direction.
Now you run 10' joists in between the two outside doubles into the center double/triple joist parallel to the ledger. Now your 12' decking runs perpendicular off the house and ledger. This is normal every day framing.
