On bigger updates ex. Photoshop 20 to Photoshop 21 the older version were kept on the machine by default. You can mark the option that the older version is deinstalled during the update installation. That's for safety if there are errors or incompatibilities with the new version. If you are happy with the new version you can deinstall the older version.
