That would be terrible to do
Not with the vertical print pack, not necessarily.
But depending on how it's used, it may be.
For instance if you use the 1x1f vertical print rotated twice on the same brick, they will still have a gap inbetween and it wouldn't actually have any overlaps.
But in general if used outside of that, used wrongly or simply used with other bricks, yes, it's a terrible thing to do.
