Auto-Save fires `DocumentBeforeSave` event - How to circumvent this?

Question

When a file is saved (on purpose) I would like to perform a certain action.
This all works with the following code:
Application.DocumentBeforeSave += new word.ApplicationEvents4_DocumentBeforeSaveEventHandler(ThisAddIn_BeforeSave);

There is only one problem, this event also fires when a change is made to the document and the 'Autorecover' function saves this change.

Is there a way to circumvent this action or at least detect if it was an auto-save?

So I've managed to find the answer to this question on this site. Essentially, this makes use of the VBA properties of a Word application I assume.

object oBasic = Application.WordBasic;
object fIsAutoSave =
        oBasic.GetType().InvokeMember(
            "IsAutosaveEvent",
            BindingFlags.GetProperty,
            null, oBasic, null);
if (int.Parse(fIsAutoSave.ToString()) == 1)
    MessageBox.Show("Is AutoSave");
else
    MessageBox.Show("Is regular save");

This solution seems to work for office 2007 and up.
