The passage around this formula
As the streamed sequence L grows large relative to the array’s dimensions, approaches one and the fill-and-drain overhead becomes negligible. But when L is comparable to r and c — a small batch, a short sequence, a matrix dimension that barely exceeds the array’s own size — the overhead is not a rounding error, it is a large fraction of every pass through the array. This is a simplified model, not a specification of any one vendor’s pipeline, but it is the same…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
