Just a thought. Irrespective of language or culture it is not common practice for ATC (and this includes the USA) to simply issue a landing clearance for another runway than for the one you are on approach for without any forewarning of any kind. Yes I know United queried it (in their own way) but should they not have seen more of a red flag simply by the manner the "amended" clearance was delivered? At the very least ATC would have transmitted "runway change to 9R, cleared to land 9R".But they would normally ask if you are able.
