When the plugin ZIP is downloaded from GitHub, and then uploaded to WordPress, the new version should overwrite the previously installed version.
If WordPress recognizes that this is the same plugin, it will prompt with a button that says "Replace current with uploaded" (screenshot).
What I experienced was that there were two simultaneous installs.
