When sending files to Amazon via email, Amazon chooses how to process the file when sending it to specific devices.
'azw' is a file name extension, it doesn't tell you what the internal file format is.
But quibbles aside, the most likely explanation is that calibre produces a 'both' file that contains both the MOBI and KF8 versions fo the book. Kindlegen produces a file that contains MOBI and KF8 AND the source ePub.
