There is much confusion about the precise execution of bars 1-2 and 9-10.

The older variant is for both pairs (1W+2M and 1M+2W) to turn RH and face each other on the midline, W above M. This pattern is asymmetric; 1W+2M make a 7/8 turn and back, 1M+2W a 5/8 turn and back.  None of the instructions mention 5/8, 7/8 or even mentions the asymmetry

Later instructions specify ½ turn, that would bring each pair to the same diagonal as where they started.

The most recent instructions add an (optional?) ¾ turn. If taken precisely this brings the pairs to the other diagonal.

For the record, here are some official descriptions; there's plenty of confusion.

My (purple, undated) copy of MMM1 (page 38) has the following original text:  
1-4	1st lady and 2nd man turn each other by the right hand for 2 skip change of step; facing up and down in the middle of the dance they set to each other.  
5-8	They turn each  other with left hands back to places, and set.  
9-16	1st man and 2nd lady do the same.  

The 1992 Manual has a note:  
Bars   1-4  1st woman and 2nd man turn to finish with 1st woman facing down and 2nd man facing up.  
Bars 9-12  1st man and 2nd woman turn to finish with 1st man facing up and 2nd woman facing down.  

The 2005 Manual does not have a note for the dance.

The 2013 Manual has a note:  
Bars 1-2  1st woman and 2nd man turn three-quarters to finish with 1st woman facing down and 2nd man facing up.  In earlier versions of these bars, 1st woman and 2nd man turn half way.  
Bars 9-10  1st man and 2nd woman turn three-quarters to finish with 1st man facing up and 2nd woman facing down. Alternatively they may turn half way.  

TACnotes 4th ed 1995 says:  
1-2  1st woman & 2nd man three-quarters turn to finish with woman facing down and man up.  
9-10  1st man and 2nd woman turn as bars 1-2.  

TACnotes 5th ed 2008 says:  
1-2  NB: In 2007 edition this is a HALF turn to face each other in middle of the set.  
9-10  2nd woman and1st man turn as bars 1-2.
