Yes, it is possible that the landlord is attempting to catch up on missed mortgage payments. However, without him showing you proof of this, there is no other way I know for you to find out. If the bankruptcy was dismissed, then the bankruptcy has nothing to do with the mortgage anymore.
The term "surrender" may or may not have any meaning at all in a case that is dismissed ("backed out" is not a proper term for anything in Bankruptcy). It is a bankruptcy term that means he will allow the lender to foreclose. If the lender does not foreclose and the case is dismissed, his intent to surrender is meaningless. The lender may or may not foreclose because of a default in payments or other reasons.
Since your landlord's Ch.13 was dismissed (probably for failure to make Plan payments), he can keep the property until it is foreclosed upon. Sounds like he wants to keep it, so he is making monthly mortgage payments.
