If the PERSON_KEY is the same (ie: 'person') for each of the entities you need to qualify against, you should be able to just use the string "person" in your qualifier.

private EOQualifier qualifierFromSender(ERD2WQueryPage sender) {
	return ERXQ.and(sender.qualifier(), ERXQ.equals("person", ((Session)sender.session().user())));
}
