When the googlebot crawler indexes sights it doesn’t have different crawlers for google.com versus google.co.jp versus other localized google sites. It has a single googlebot that indexes pages and doesn’t provide a language header. With the change, google would not appear to have interpreted the page in any way different, which is the case because it doesn’t get any different HTML.

@Simon Content negotiation is bad because search engines will only be able to see one of the versions (and might never see the other one). Also, many users (including me) don’t like it when they click on a search result that is not shown in the same language as their query (and the snippet) (actually, I personally don’t just not like it, it makes me quite mad ).
