AFAIK, "dual old mobi" is an oxymoron. There is no dual
old mobi (do you mean KF8?); in Calibre, that's AZW or AZW3, whichever is Calibre's versus KDP's. (I can never remember. Yes, it's peculiar, what can I say?).
There is, even to this day, Old MOBI/KF7, or Dual MOBI (AZW-whatever) for Calibre. Now, if you
mean a MOBI
made by someone else, a "KF8" mobi, then yes, you can have a file with dual interior files with the file extension of MOBI.
It's unclear to me if we mean "files from anywhere," or "files made by Calibre," so...that's my clarification. IF files made somewhere else, by somebody else, are included in the discussion, then yes, there are 3 possibilities in the MOBI family.
