There is no difference in direction, but there could be a difference in overlapping, pressure, and products used.
Permanent coatings obviously take more time and thought, but even semi permanent coatings and sealants can create high spots. Directions generally include straight line passes in one direction, followed by perpendicular passes to create a hatched effect which ensures even coverage. Some waxes and sealants suggest a second coat to provide even coverage, whereas others discourage it because the solvents used in waxes/sealants can strip the previous coat, or conversely, create high spots.
Straight line does allow for better paint correction in the event that you do have debris caught under your applicator and induce marring.
