Go back to the original video(s) of her leaving the 9/11 Ceremony. Does she enter the vehicle on the left or the right? It can't be both.
As for the other photos, they may or may not be reversed. They may also be different vans.
I looked for still photos of the van facing left but couldn't find any.

Okay, fine. Prove it.
Yes, there are two vans. One is a GM. The other is a Chevrolet. But, they are mechanically identical. (See: Scooby TWO! Hillary doesn't have just one Mystery Machine; she has TWO (and a motorcade) to meet 'ordinary' Americans)
I looked for still photos of the van facing left but couldn't find any.
Easy-peasy.
The left-side of the Chevy:
The right side of the Chevy
Notice that it has the yellow NY license plate and has doors on both sides.
