Today, some tire lug patterns are directional, and can't be crossed. Tires with good rain drainage channels are examples.
The no-rotate advice used to be common for early steel belted radial tires, in the belief that with the softer sidewall, the belt takes a set based in forces in one direction and might cause eneven wear if crossed. I think it turned out to be hogwash, but the advice stuck around anyway.
