That's an interesting thought, but I don't think it's referring to that theory, which looks like it centres on ideas, whereas here it's talking about the more visual sphere of form, as a component of art:
http://www.getty.edu/education/teachers/building_lessons/for..."The form of a work is its shape, including its volume or perceived volume. A three-dimensional artwork has depth as well as width and height. Three-dimensional form is the basis of sculpture.[1] However, two-dimensional artwork can achieve the illusion of form with the use of perspective and/or shading or modelling techniques.[2][3] Formalism is the analysis of works by their form or shapes in art history or archeology."
