I found in these situations, it's actually less helpful to pick the rule wording apart, but to instead think about what the Dev's actual "Intent" for the rule was.
In this case, the Pet bonuse was so the Beastmaster has has an extra powerful pet. And the Deathlock to prevent healing or gaining life.
So the question is, did the Devs mean for Deathlock to "undo" the Beastmaster's pet bonus? My guess is no, but time will tell.
