I've never heard of this, but I know that with Mopar, you should never say never.
The "normal" setup is to have left hand threads on the left side & right hand threads on the right side. This went on until somewhere around 1970 (I think), then they switched to right hand threads all around.
I was told the idea was that, when slowing down, left hand threads would tend to tighten on the left side & right hand threads would tend to tighten on the right side. It makes sense, but it was probably over-engineering. The left hand studs on my car have an "L" stamped on the end to indicate they are left hand threads. Unfortunately, when you use standard mag type lug nuts you can't see the L, but the left handed mag lug nuts I used to have had notches on corners to show they were left handed. But you're not gonna' let anybody else change your wheels for you anyway, right? :-D
