All of the controllers will execute if it is not specified, but the order is never guaranteed. The documentation does say that what will be shown will be overwritten by extension 1 but it does not state that the other extensions will not be executed, with the keyword being overwritten (potentially meaning it did execute but it will not be the final value returned). https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_controller_extension.htm
