I know that. The reason that I suggest one direction is that this motion tends to be used with less pressure and also avoids going back an forth over the same areas several times with dirt already on the cloth- I rotate the cloth continually using a clean square folded cotton cloth ( 8 clean sides to a 10X10 cloth folded into a square and used on both sides ) So I can use two clean sides of the cloth per quadrant of the table.Cold water. Never use hot water on worsted wool.
Not necessary as Simonis isn't directional.
