It does, 3.1.3(b).

Basically since Primal is multi-platform in the way that it is, a user can purchase “pre-paid zaps” outside of the iOS app and use them within the iOS app as long as these “pre-paid zaps” can also be purchased within the iOS app via in-app purchase and with Apple taking their cut on that purchase. So there's no forced exclusivity in some multi-platform cases. All of those boxes are ticked for Primal. Money coming in to the wallet from outside can be framed as "pre-paid zaps" purchased on another platform. It’s all just semantics, and clearly the Primal team knows what semantics are at play are and how to frame them, no real wizardry .
