I have never heard of anyone referring to the front
end of the yaw string being the way that it is pointing.

Really? I picked it up somewhere in my instruction. Something to the
effect of "Think of the yaw string as an arrow with the head attached to
the canopy. It points to the the rudder pedal you need to push to
coordinate."
Seemed very natural and simple to me.
