It's still rather misleading, "Completely Disable..."
I thought so too at first but I guess whereas the title now says "Completely Disable Intel AMT on Windows", it probably used to say something along the lines of "Completely Disable Intel ME on Windows".
Edit: The title has been changed again and now reads "Disabling Intel AMT on Windows". That's better and less confusing.
It's worth mentioning that on some systems it's possible to permanently disable the management engine and the MEBx extension BIOS by selecting the "Permanently Disable" option from BIOS.
