I had the same reservations about this as well and ended up stumbling on this article which helped clarify my thoughts on it a bit: https://plato.stanford.edu/entries/morality-definition/

Whilst not really settling the debate about which moral framework is used it does give a good lens by which to judge it, from the article:

There does not seem to be much reason to think that a single definition of morality will be applicable to all moral discussions. One reason for this is that “morality” seems to be used in two distinct broad senses: a descriptive sense and a normative sense. More particularly, the term “morality” can be used either

1.descriptively to refer to certain codes of conduct put forward by a society or a group (such as a religion), or accepted by an individual for her own behavior, or 2.normatively to refer to a code of conduct that, given specified conditions, would be put forward by all rational people.
