Is the author some sort of anti lockdown person? From the licence: https://github.com/sadaszewski/focker/blob/master/LICENSE#L9
definitely, he somehow thinks he can have two incompatible licenses on the same piece of software. Does that invalidate both of them?
If it was about two licenses, it wouldn't be a big deal (aside of being a pile of harmful bullshit, of course). But it's not - it's a single license with conflicting terms. A license is supposed to give the user an assurance of ability to use and/or distribute the software as long as they obey the stated rules, so if you get conflicting rules, such assurance is essentially useless.
