Well he's using DoL as a facade. I'd assume that whoever on Patreon is in charge for checking their creators content would only see a download for DoL, unless they were to subscribe and get to see the external download link to an illegal version of his project (this last part here is kinda questionable, I'd think that they could find out about it in more ways other than via subscription, lol). L&P would surely be in for a treatment if they found out about this. Wouldn't be surprised if he'd face a lawsuit resulting in a juicy fine, if not worse.
Edit: All it really takes is an upset patron reporting L&P's wrongdoings. Weird enough that Patreon didn't find out about it themselves yet. One would think that they'd have the tools to easily do that.
