In the second form of dependent goodness, the other purpose is fulfilled alongside the commanded act, rather than afterward.
Consider funeral prayer for a Muslim deceased. Looking only at the outward posture in front of a body could obscure its purpose. The prayer is not worship of that body: it fulfills the Muslim deceased's right.
That right is fulfilled with the funeral prayer itself, not by a later prayer as in the Wudu example. The deceased's Islam is the intermediary in this classification; it is treated here as a voluntary human act.
