Unless I have completely misunderstood you or the meaning of alt account, then it absolutely is.

I think lets assume I've misunderstood what alt account means, because thats likely. I've never seen a use for them for myself, so never really had more than a casual understanding. If the primary use is to have an account that has no outward association with the other account, then I think I was using the term 'alt account' wrong.

In which case you simply have two accounts associated by name and network (network is, activitypub -> lemmy), but differing by instance (website). The separation by instance is the key difference. This means they are separate organisations participating in the same market. Whats acceptable on one site, might not be acceptable on the other. The difference between instances on lemmy is a bit like the differences between grocery stores. The instances all play in the same market (just like coles, woolies, aldi, iga, spudshed are all in the grocery market) and are similar. But you dont get all the same stuff from an IGA that you do from an Aldi. The quality can be vastly different, just like the difference between spudshed and woolworths. Of course we're comparing organisations run for a profit to organisations run for socialisation and information dissemination purposes so the similarities stop somewhere 😆😆

As an in practice example, the site rules are similar but different. For instance the legal systems they refer to and rely on are different. Lemmy.world is likely governed and hosted in the US, whereas aussie.zone is hosted in Australia, and is explicitly governed by Australian law, in the first case. In front page sidebar 'nothing illegal in Australia' can be read as a declaration of the site owners preferred location of legal proceedings as well as indicating the legal structures to be applied while interacting with the site.
