The one most recognizable part of the structure is the ring, which the artist establishes in panel 2. There's clearly nothing to the left of it, and she's heading to the right of it. There's a straight line between the two characters. In panel 3 there's still a straight line, she hasn't gone very far (although he's had time to go from rearing back to a full run, nice trick) and yet she's now on the opposite side of that very recognizable element. There's still a straight line between the two characters, and he hasn't moved very far, which means the ring must have got up and moved on its own.

That, my friend, is crap continuity, and just plain sloppy. Amateur quality work at best.

Oh, and I know there's very little to the left of the ring. Know why? Because the artist shows us that in panel 2.
