they are defiantly the same person, neither account was recently sold, and from the looks of it he defaulted on the loan (although the lender did not appear to provide a repayment address). According to the lender's thread, the repayment address should always be 1KvdN7tm9Vf6Mx2XRG3EhzdhtxxHDpZkLq (although the borrower should always check with the lender prior to sending a repayment to this address), which is the address the loan was funded from and it is clear that no repayments of any amounts above .2 were made to that address.
I had the same question, this thread[1] should answer it. The collateral was sold at a loss.
