Because there is little to no voltage difference between 100 and 200, and leakage current dominates at this frequency, it's better to hit AFTR or LPA idle than to clock down.
In short - disable 100 MHz and you get free "Wheatley".
I agree your assessment on the 100Mhz not saving much or any at all. I started disabling it 3 weeks ago.
