In that video, he is going over the surgical possibilities with someone CONVERSANT in the software he's using who will be preparing a SPLINT (or a bone buttress material shaped for what ever graft they might need) based on the surgical plan. It isn't a TUTORIAL that a patient is going to get from the doctor using the software.
If you are in any way conveying to Birbe that you expect a long sit down 'show and tell' tutorial session with the software before you decide to have the surgery, he might be thinking in terms of: 'NOT enough TIME to address all the contingencies this patient has in the decision making process.'
As to his doing the posterior down graft, you already had access to that information that was in his toolbox on another part of this forum where a patient relayed the posterior downgraft was offered to her.
ETA: If another doctor offers such, (I see that the doc in the video is asking over $600 for that sort of consult), then you have option of paying for it with doctors who offer that option. But one doctor's plan might not be the same plan of another doctor.
