SDLT Query involving a newly formed Trust

We have recently set up a Trust for two of our children (adults with disability). Another of our adult children (Person C) is a trustee of the Trust along with ourselves. The trust deed has the two disabled children as primary beneficiaries and states that only in the event of their death, could their sibling Person C become a discretionary beneficiary. My question regards a future where both a property is purchased by the trust for the Primary Beneficiaries (in their lifetime), and a property is purchased by Person C. Would I be correct in understanding that neither would incur a higher rate charge SDLT, given the lifetime clause in the trust deed mentioned above (and that there is no additional property ownership by Trust or Person C)?
