No, Ergo doesn't have netsplits because there isn't anything to split with. The point does not apply.
There are events that may affect more than one machine which are not netsplits.
e.g. an ISP with common users experiences an outage, an IRC client with common users has a bug, common users within the same time zone have automated system updates run at the same time, the IRC server experiences an upstream network disruption affecting only some routes, a regional power outage occurs, a hosted bouncer service with common users has an outage, etc, etc, etc...
