Dear Helmut,

uups, you have caught me red handed!

My statement came from the factor 2 in the sample size formula on page 757, containing the number of subjects per sequence.
But I forgot here we have four sequences compared to two of the classical 2x2 cross-over.

Lesson learned: Think twice and check ones assumptions before touting it half-cooked to the audience. Sorry.
