I like to think of it this way . . . when people see the movie alot of them think "OMG!!!1!!11! It's Johnny Depp!!!111111111111_1". Here, they won't do that, and since he doesn't look like Johnny Depp in his face and he DOES look like Jack Sparrow in his attire and mannerisms, people will think of him as Jack Sparrow. They don't know who this guy really is. In the movie, even if it's subliminally, you know it's Johnny Depp, and while it's a fantastic performance he puts on, it's difficult to be completely Immersed knowing his 'alter ego". Here, they don't know of an alter ego, and so he is just Jack Sparrow. In that way, the audience will become that much more immersed in the magic. Subliminally. Yes.
