Reference of "them"

Does the highlighted "them" refer to "masochistic drives"?

Text:

More tellingly for the parameters of this book are the ramifications of Freud’s relational components of masochism and sadism. The result of sadism is war, whereas, although unreflective masochism in life is also destructive of relations, art can channel the masochistic drives so as to give expression to aggression in a way that makes them available for cultural becoming rather than extinction.
