Can a dev confirm/deny this analysis is correct?

Unfortunately the code could benefit from some cleaning up to make it more clear what it does, can't really tell for sure myself without running a small testnet.

If the analysis is correct, what needs to be done to modify the total order rule so that TXNs are confirmed in parallel (main chain -> main tree)? I gather it would complicate the code a bit, but it would be a shame keeping XDAG stuck up like it seems to be.
