Normally you wouldn’t contrive to use embedded struct fields in this way. And you can’t have the same kind of composition with methods - it’s a compiler error:

So the whole article is basically about using the language in a way you normally would ever do.

This can be simplified, conflicting field names at the same level also don't compile:

Conflicting functions at nested levels also compile:

It's not about method vs field, it's about the nesting level of the conflicting identifier, if it's at the same level there's an error, if it's at different levels, the higher level hides the lower level identifier:
