It is certainly possible. A plume often makes a whole 360 degrees turn and a large part of it is of the same width, so it could be written in either direction with about the same effort. What is not possible in my experience is making two thick strokes going in opposite directions without some very awkward repositioning of the quill or the hand (so, I see no way to write a typical a in one stroke, even when both the top and the base are merged).
One thing that speaks in favour of your interpretation is the misalignment of strokes in s in my previous image. If s was written in one go from the top down it would be natural just to do it in one stroke. Here it was obviously done in two strokes, because the end of the plume crosses the top of the base.
