the man is doing a turn there, and as you noticed, the figure looks like like a U-turn. But I don't think there supposed to be a heel turn. Maybe it looks like feet are together because the steps are small?
mans steps during this turn seem to me more like rocking in place
so the figure (man's part) looks like this to me:
2 walks(slow slow, roughly along LOD),
rock rock rock (in place, while turning, QQS)
lunge (counted slow. sharp step forward, against LOD)
can't find the book around, but I'll find it if you still have questions about this step.
in syllabus I know both parts for pretty much all steps I danced. I was very thorough. In open I don't even want to be so thorough: the routines are too long and I struggle to remember my own footwork and steps right now. sigh. I wish one day I'll be in control again...
