Variables do not change on their own.  They change because of a poorly written lisp routine or when a user abruptly exits a command in an unconventional manner.

My point is that variables like Elevation just don't mysteriously change all by themselves.

No, I would not change what you have.

So are you saying StabiCAD is responsible for the elevation being changed without your direct input?

Since you are using AutoCAD 2014 why not record a macro, save it, then replay it every time you need to?  This feature is called the Action Recorder and it can be found on the Manage tab.

The use of the Action Recorder is covered in your AutoCAD Help file.  You start the Recorder, run through all the commands you normally would then stop the Recorder.  You assign the macro an unique name and Play it back whenever required.

One of the macros I created with the Action Recorder purges and audits a drawing, then it does a zoom > extents and finally starts the save command.

The Action Recorder creates macros; it does NOT create lisp routines.

Use whatever method you want.  No one is forcing you to do anything.

I see no benefit to coupling a change in elevation back to zero with autosave.  It makes no sense.  But you can do anything you like; it's your computer and your drawing.
