There is one notable caveat to this scenario as well, however. If the BIP110 chain were to overtake the original chain in length later on (due to miners moving to the BIP110 chain), all nodes — Core and Knots alike — would accept the BIP110 chain as the only chain. The original chain would in this case be discarded, or wiped out.

Nit: wipeout occurs of course when the total work of one chaintip exceeds the other, not when it is longer.
