Update, I have found something on the CASE site to support my opinion:
The individual sponsors of the collecting donor should not be counted as donors for the purposes of this survey. Some platforms provide the sponsor with the opportunity to opt-in to hearing more from the charity. For donors who opt-in, you may choose to import their details and create entity records for them in order to steward them for future possible dona-tions. As such you may wish to give them soft credit for their donation(s), though only the collecting donor can be counted as a donor in donor numbers for CASE AMAtlasSM purposes.
