This is not mental gymnastics. Just feel how it spins and reinforce the pattern. For some people, it will spin to the left; for others, to the right; and yet others will have it spinning in both directions at the same time. In the last case, it can be that one of the pyramids goes one way on the vertical axis, and the other the other ways; but there is also the possibility that the whole thing is spinning both ways at the same time. This is because this constructs are above the 3rd dimensions, so things like that can happen. Only the third dimension has boring limitations of this type.
