I've never known a sky move in a direction like that. Here's my interpretation of your pic that shows that there is nothing wrong with the cloud movement between shots.
Now an easy way to prove this is this:
Go outside on a cloudy day, not a stormy day, when you can clearly see the clouds moving. Now you need to stand in a potion that you can see the clouds both in front and behind you. Now stand so that the clouds are moving in your vision from left to right (as they are in the first shot) now turn exactly 180 degrees and now you can see that the clouds are moving from right to left.
A... yes... quite right, quite right.
Sorry about the migraines. Did you see a doctor?
