VDML11 — Imprecise statement about Activity Value contributions

In sub-clause 7.1.9 (Activity), page 22, it says: "Conversely, all values can be traced back to their contributors. This is possible, because VDML is not representing the actual paths of each unit of production, but rather the statistical use of various Activities that contribute to results achieved over some period of time. That representative set of results includes some Activities that are only active for some units of production due to product features, operating exceptions, defects, repairs, sample testing, machine failures, and so on." The word "includes" (see above in bold) sounds strange to me. Because Activities are not included in a set of results. Is maybe a different verb meant or was it meant to say something different ?
