Where do people end up after bar 6 of a quick-time chain progression? [Strathspey Q&A]

I do not have the Birmingham book in front of me, but, I am pretty sure that you will find that the deviser has given different instructions for the 'chain progression' when danced to reels and jigs as against strathspeys - not that any teacher I know (including myself) observes the difference.

[I just posted this question on »Strathspey Q&A« but would like to repeat it
here to give it more exposure. Feel free to answer on Q&A, or post something
here and I'll summarise any answers to Q&A later (or vice-versa). – Anselm]

I used to be under the impression that the quick-time »chain progression« went
as follows:

1-2: 1st and 2nd couples, giving right hands, turn ¾ round into a line up and
down the centre of the set.

3-6: 1st man and 2nd woman, giving left hands, turn 1½ times round while 1st
woman and 2nd man chase clockwise half-way round to the other end of the line.
Everybody finishes in another straight line of four.

7-8: 1st and 2nd couples, giving right hands to partners, turn ¾ round to
finish on own sides.

This is also the way this formation is described on the RSCDS web site.

The chain progression was originally introduced in the 1973 Birmingham Book,
and the description there contains a figure for the positions to be reached at
the end of bar 6, which very obviously shows the four dancers not in a line of
four down the centre of the set, but 45 degrees clockwise on from that
position, in two offset diagonals.

Is that a mistake in the book, or have I been doing (and teaching) the
formation incorrectly all these years?
