Yes, you might be right, it just look as if it's his left leg, but yes I think Kishi meant it as his right leg. Good job on using your Byakugan, Hinata hime.i did some observing of my own, but i think the band thing on page 7 actually is his right leg, it just looks funny with the black pants and the way he's facing...and plus, all the times he had no band, he also had no vest, so it could be he just took that stuff off while he was resting...not that i think he's to blame, though.
Anyway like I said, the manga is read from right to left and then top to bottom, so if Sakura was tending Neji and another 'Neji' was walking outside the tent then definitely there was a Neji clone. Problem solved.
