The extra details exhibited in this passage away from Jesus makes me think that there are multiple testimonies recorded here. Either by some disciples stepping aside from the Jesus crowd and following up on this healing, or by people that had occasion later to follow up with the disciples that had witnessed, or by the man returning to the disciples himself, or by all of the above. It is obvious that these are details collected from others as is much of the Gospels, one writer collecting and organizing many peoples testimonies. All the more reason to believe the Gospels.
