I'm a little unsure what order things happen in behind the scenes, maybe hash assignment is done one entry at a time

Parens have higher precedence than the assignment operator, so the list (nit: it's a "list", not an "array") is contructed before the assignment is performed. This isn't a hash constructor. There isn't such a thing in Perl. The code creates a list, which is then assigned to the hash.
