For what it's worth, this article is probably better titled "the Italian-American Bakery Explained"; over the last century and a half Italian-American culture has evolved in to something with roots in, but distinct and different from, the culture of Italy itself. It's largely based on the culture of Sicily and the South, since that's where so many Italian immigrants came from, but years and years in America have shifted it in to a sort of separate culture. It's especially telling that this is from a New Jersey-focused website, since NJ is one of the epicenters of Italian-American culture in the US.

I'm a fourth-generation Italian-American myself, and I've recently been learning Italian and gotten interested in geneology and tracing the cultural roots of my family. It's really interesting to see how true Italian culture is similar to what I grew up with, but also very different.
