Could have been Gandalf, Treebeard did see him before anyone else did, and G. barely remembered his own name at that point (was somewhat detached from earthly life at that moment). I think the horses pulled loose themselves when they heard Shadowfax.

But it would be just like Saruman to be too eager to check on his orcs' prize. Not much of a tactician. Remember how he emptied Orthanc and stood outside the gates watching his magnificent army go? Hid once the ents showed, made a break for his tower behind their backs.

Well I guess that clears that up. lol.
