not being a specialist at all of RN turning instructions, I think that this change of position would be true if the turn was ordered by "White Pendant" (in Italian: "per contromarcia" or by "counter-march") that would mean that the ship stationed behind follows the leading ship (in her wake if stationed exactly behind) in order to preserve relative bearing and distance.
Capt.Leach always mentions "Blue Pendant" turns (in Italian "a un tempo" or "at one time"). They would imply that the 2 ships execute the turn together and therefore only absolute bearings and distance are preserved. Of course a small speed/rudder adjustment can be needed to maintain the exact position......
I think only "Red (Compass) Pendant" turns imply speed adjustments between different divisions (columns), but this is only related to a full maneuvering fleet (e.g. at Jutland).....
If the course change at 2:03 was a "Blue" one while PoW was on Hood starboard side, then PoW would end on Hood port side after the turn to 200°.
