Malefics squaring their own domiciled rulers - methodological contradictions?

For example, Sag Saturn right-hand square to Jupiter in Pisces. Generally speaking, would such configurations imply the malefic being strengthened and/or bonified, and the ruler maltreated? Because IIRC in Brennan's and George's books, one of the conditions for maltreatment was overcoming from behind by malefic, while one of the conditions for bonification was being ruled by a well-positioned benefic. How to resolve such potential contradictions, especially when 'reception' is taken into account?
