display position?

Greetings!

Just curious, what is meant by "display position"?

It occurs these three times and no where else in the draft.

I am assuming it is a reference to the existence of a location in a 
matrix for the storage of a value that is part of a matrix result but 
why call it "display position?" Is there some significance to that?

Hope everyone is having a great weekend!

Patrick

PS: Sure, have to take out the examples, "the few rules" language, etc. 
but focusing here on the "display position" language.
