Beachte auch, dass \foreach die auszuführenden Anweisungen laut Anleitung mit einer Gruppe umschließt. Übrigens bietet etoolbox (das wird auch von xpatch geladen) selbst ebenfalls Listenverarbeitungsbefehle.

Weil da explizite Klammern stehen. \foreach expandiert die Liste nur, wenn man \forach in \list verwendet, wobei \def\list{1,2,3}. In deinem Fall also \edef\list{\EigeneUmgebungen, \StandardUmgebungen}.

Ganzes Bsp.:
