why is there 1 stroke when you write the 'oblong part' of the radical for 'road' and 2 when you write the one for 'stretch' even though the movement seems to be the same? i.e. it's stroke that goes from left to right to left to right just like top of the '乃', so it shouldn't be treated as interruption of flow??? is it just an exception or is there some reason for it?

PS highlighted the parts I meant w/ yellow colour
