It's simple to explain in the context of this discussion. But probably doesn't seem as simple to the average user, who wants to donate $1 to a creator, and will feel like some kind of scam is going on if they are asked to add $10 to their Patreon balance first.

Thinking about it some more, Patreon may end up eating the additional fees for the first payment (for CUF posts), increasing their cut a bit on other posts to make up for that, then aggregating the recurring charges.
