That's dialects though. The same could be said for most regions in the UK from people living in the UK or abroad, e.g., a Scouse understanding a Glaswegian. This is similar in Italia across regions.
They are dialects. Swiss German isn't a language but a group of dialects, but they aren't closer to high German than Czech is to Polish.
I think my point stands that it's a distinct language from the official one. It definitely feels like that in practice where a lot swiss people feel like they have to wear their official hat when speaking regular German and they prefer to have casual beer conversation in English rather than high German.
