There was an explicit "or", it wasn't just two clauses in a list. And "or" vs "xor" doesn't make any sense here, if it were "xor" then Google would own anything you did by actual default (i.e. that had neither anything to do with Google's business nor resulted from work done for Google), which makes no sense. It is explicitly an "or" and clearly means inclusive or, not exclusive or.
