Note that the minimum distance a ZigZag Bishop moves is a Zebra's move away: One orthogonal and TWO diagonally outwards.
Think of it as a zig then a zag followed by 1 or more spaces along the diagonal as a bishop. Or it slides 1 or more like a biship first and then zags 1 more in same direction and then zigs.
ZigZag Rook's minimum distance is a camel's move away Two orthogonal and one diagonally outwards.
So its 1 or more spaces as a Rook followed by a zig in same direction and then a zag.
Or a Zag diagonally then a zig and then moves 1 space or more like a rook in same direction.
So not only they cannot move to adjacent squares, they cannot move to squares a knight's move away. (This is unlike the duke and cavalier that can move a knight's move away.)
