I'd move the footnote indicator to:
Available for point[a], box, path, circle.
Available for point[b], box, path, circle.
As the footnote only applies to that specific left operand type.
Or maybe:
Available for box, path, and circle. It is also defined for point [a] but
it has no related physical meaning.
