    Because you want to know the relationship between the +2 and +1 forms. So you start with the +2 version, which is with just the hydroxyl deprotonated, so the next proton to be lost comes from the NH in the ring, pKa 6.1. Going from the +2 to the +1 is entirely based upon that group losing or gaining a proton.
