Marjorie McLaughlin writes:  There are three mistakes in the video and, as they are done the same way by all of the dancers, I assume it was taught incorrectly, as opposed to a mistake by a single couple.

Bars 1 - 2  the ladies dance a Petronella turn to face partners on a diagonal line.  In the video the gentlemen are moving slightly right and left to form a straight line, which is incorrect.  

Bars 5-8 the turns are Right Hand turns, not two-hand turns as shown in the video.

Bars 29-32 both couples turn partner Right Hands to face ready for the next repetition, not two-hand turns as shown in the video.
