When I try to hold Disembowel when I do the normal opener, it falls off a split second before the hand becomes vulnerable. Maybe this has to to with latency differences, I don't know. However, I do know that I get B4B on that Phlebotomize.

EDIT: Maybe your scholar uses selene during this phase? Ours prefers Eos
Just use double Impulse Drive, thats my way. BotD dont fall off and combo neither. Spam click on enemy list and in the same time Disembowel when the boss return vulnerable, thats work for me.
