Continuing Steps in Karate

This is a follow-up to my earlier post: What was the original kata? We know that kata have changed - even a cursory glance at youtube will show you the huge variety of ways that any given kata can be performed.  This appears to not be just a modern development, as even by looking at books from the 1920s, 1930s, 1950s etc... we can see that there have been changes to kata since then, and even at the time (compare, for instance, the earlier publications of Funkoshi such as Tote-Jitsu (1922) with his later publication, the Karate-do Kyohan (1931) and then with its re-working in the 1950s; or compare the two earlier works and their rendition of naihanchi kata with Motobu's Karate - My Art (1932)).  Even within the students of the same teacher, we can see variance that cannot all have been contained within what was originally taught (see the different schools of the students of Choshin Chibana, for instance - the differences in kata between Kyudokan and Matsubayashi-ryu are a good examp

Just a random thought - it's generally held that when turning, or changing direction in kata, the sequence is head-feet-hands.  But, what if the sequence finishes after the turn?  What order should it be then?   Some places where this does occur, or could occur, are in kururunfa with the west and east open-hand soto ukes; sanseru with the 4-directions technique sequences; and in seisan, particularly on the first 180 degree turn.
