Yes, Auto save is an internal feature in Maya.
It does an incremental save after a certain amount of time based on time specified in the System Preference.
Auto save is not enabled by default.
In order to make best use of this plugin I would recommend using it with a project and not with an individual Maya file, because autosave function saves the incremental files in under autosave directory in the project set.
