It seems that the displacement of the dimensioning line is dependent on the order of the point picks, although the label seems to have its own way. In the attached image I picked the upper line clicking on the left point and then finishing on right point. The lower line I have picked first the right point and finished with the left point.
I think that if the label were attached in someway to the dimensioning line, this could be an useful feature.
