If the person the baby is with is truly safe it shouldn't be an issue revealing that. A best scenario could mean that they've found someone safe and suitable and through the proper process could be a suitable carer agreed with SS. I agree it's a very real prospect baby is with someone, I'm dubious about why they aren't revealing this.
Rationally at this stage they will be being advised to be open and honest to stand the best prospects going forward.
