Open gangways and articulation are not synonymous. By your definition the 357 is articulated, but there are doors around the gangway. An articulated train has two cars share a bogie rather than individual bogies underneath. The Paris Metro had an articulated car model that did not have open gangways. Meanwhile the 707 isn’t articulated as the cars have their own bogies but has open gangways.
