No I use the slash for palm facing parallel to the floor in my teaching style. 
 In one of the lessons he was using the slash across the palms for palm up and 
away or down and away (parallel to arrows).  I'm teaching handwriting as well as 
computer writing.

If I were to use the slash as up and out, I'd put it at the tip of the hand so I 
could conceivably write palm up and and out, (slash at the tip) and palm up and 
back (dot on the tip).  If you put a dark circle above the tip, you squeeze the 
hand, and in the middle it could be a thumb projecting. 

I will make this into a PDF so you see what I mean from my lessons. It applies 
to every hand so that now you can show all those 45 degree variants that are 
sometimes a real challenge to write.  I'm still experimenting.

Oh yes, it's great to see Stefan and his students use the blackboard
and chalk to write SW! I was very impressed!
