There are many layers to "being familiar with anglo culture"... being able to understand technical documentation to a degree won't cut it in many cases.
I went through several stages of learning retroactively (i.e. not appropriate to my age) through dating or having otherwise good relationships with someone from the US. So, for example, I've learned about TV shows like Daria or Dr. Who many years after they came out. (And yes, I've learned about Dr. Who from an American friend, and before that I didn't know there's a thing for more educated Americans where they think that Brits are more... refined, not sure if that's the right word).
I'm married to someone born in the US, so, through her and the need of dealing with the kid who grows up primarily speaking English I've learned nursery rhymes, lullabies and a bunch of kids folklore that I would've never come in touch with in my line of work.
More than that, you can perfectly well live in another country and never really know the side of life of the locals if you are never invited to visit, or don't develop very good relationships with the locals. You might never know what home-cooked food looks like because you'd only have access to store-bought or restaurant meals. (Eg. I didn't know that mac-and-cheese was such a common food in the US until I was invited to visit someone in an informal setting). And there's plenty more of it. It'd take a book to try to enumerate all of these.
This both affects the less formal communication one may have with their peers as well as contributes to cultural mixups especially when it comes to customer-facing interfaces.
