That sounds right to me. AFAIK they never made an Export version for Western markets, the "Export" versions were for use in Asia. Same applies for Continuum Shift 2 for example (I think they had an Export version of this, but I could be mistaken). It definitely worked offline though and did not require network access.
Important to point out that Export SSF4 never got updated to Ver. 2012.
Thank you for the insight @kazuo. Even though you did not get an export SSF4 1.3 (2012), you can easily change the language to English in the settings ?
