I was addressing your question whether he was a Phalangite, Hypaspist or Peltastai Makedonikoi.
If he has a standard, he is a standard bearer.
Regarding the shield on his right, the image was mirrored because of another detail (originally he had its shield on his left as it should be). It can be excused because the phalangite is not represented on a combat stance, and is resting (having a sip as you can see). Thus, he might have found more comfortable to have the heavy shield in his stronger right arm while his sword is sheathed.
