I'm not quite sure I understand - but the Emulator stores the contents of 'storage' in the web browser's 'local storage'... So I guess if you used a different web browser (or an emulator hosted from github vs espruino.com you would have different storage contents)
Also, you might have just been uploading to 'RAM' when you tested? In which case it won't overwrite the old one...
