When they say about desctructive / non-destructive editing, they usually mean way of audio data editing, not what happens with files, where processed data are stored.
About differences between loaded and saved data - with Audacity you can export to the same file, as loaded from. And in mhWaveEdit (as much as all other) - "Save As" action is still there.
