Don't you have to reverse the twist for every other loop, or you are
creating twists in the line ? I just do a figure 8 loop instead.

I think Roger's talking about untwisting the tail of the rope as he coils. A
problem I've seen with the over and under technique (which I think is what
you mean) is that it's really easy to produce a long string of evenly spaced
knots when uncoiling it.
