Then who would generate the Multi sig address? If the escrow himself generated the keys, there is a high chance that he also has control to all of the keys since he can just paste them off somewhere around his machine.
This is precisely why I wanted someone more experienced to weigh in. Great observation. Question, if theoretically an automated service existed that generated such a multisignature address, and then sent a key to each person in the transaction without revealing the other keys to any single individual, would it be more feasible?
