Backing up, and backing up a hill changed the dynamics of the usual one wheel peel being the right one. The reason it is usually the right is due to rotation direction and such, it isn't written in stone that one wheel peel happens in a certain way every time.
My dad thought I had trac loc in my 89. I had to move my 63 Falcon and my 82 f-150, and the most logical way to do that was the 89 Cougar (I know...). In the dirt it did a fine job of pulling them (the Falcon has 4 flat tires and was about 8 inches deep in the dirt) and I never spun a tire (more than 1/4 of a turn anyways) and just got the job done. My dad told me it had to be a trac loc, so I chained it back up to the truck, left it in gear, and let it rip, burying one side of the car. Amazing what a low HP/TQ high geared car will do. I wasn't to tough on the tranny, I had one of those stretchy ropes and snatched it with a little slack to get them going and they just followed.
