I can make it miss gear shifts if I specifically try to shift as fast as I can, but I haven't had a single issue with it in normal use. I don't understand how you can actually need to down/upshift so quickly that the double-shift protection ignores it. I can't pretend any knowledge of real-life sequential shift mechanisms and how fast they allow a driver to shift gears, but it does *feel* like a reasonable limitation to me.
This wasn't implemented as a "limitation" however, if I remember correctly. I remember posts a while back about some users' DFP paddles unintentionally triggering two shifts with one pull?
Either way, I haven't personally had any problem with it.
EDIT: Oh, just noticed I hadn't read the last part of this page and it looks like you figured out the issue with the shifts.
