Yes, but you are locked out of the dive computer functions, which I took to be the question.

Personally I would prefer that any computer I have not lock me out irrespective of any perceived transgression. My Cressi Giotto will lock up if any deco stop is missed and not corrected within 2 minutes (it appears that it will immediately lock up at the 2 min limit and not wait until I have surfaced). That means if I choose to cut a stop by even a minute, I am locked out for 48 hrs irrespective of the reason why. That seems very heavy handed to what is a theoretical line in the sand. Also once the dive has started I can't change conservatism.
Better the computer that lets you see how you placed WRT loadings and lets you make the choice without locking you up. If I have an issue during a dive with the Perdix as my DC, I can alter the GF LO/HI to allow a hastier ascent (but still within Buhlman). It will not lock me out if I miss a stop but will recalc on the fly to adjust my stops.

Your computer will lock out, if you ascend above your deco ceiling for more than 2mins (in your case)
Please provide realistic examples as to why you'd do this?
What reasons would you choose to ditch your plan and blow through your stops? Do you have a back up plan or just intending to fly the back up computer?
I don't do big deco dives. I only do baby deco dives (max 50ish m), with 1, maybe 2 rich mixes for Accel deco. In almost 200 baby deco dives, I've not yet needed to abandon my stops, and never locked a computer in 800 dives.
I also can't imagine a situation where I'd dump my deco, and then be in a rush to get back into the water within 48hrs
Am I missing something ?
Probably the fact that most lock outs aren't the result of actual missed deco, but some type of user misunderstanding of how their computer works.
When I was diving my Prism 2 with a Shearwater Petrel as a back-up I surfaced once with it claiming that I had missed some mandatory deco because for some reason, probably error on my part, it hadn't tracked the unit's Predator controller accurately. I acknowledged the complaint and went about my business, glad that it didn't go into a snit and turn itself into a bottom timer for 24 or 48 hours.
Known in the "it" business as PEBCAK, "too dumb to own a computer", and many others all the way back to the "kind of confusion of ideas one is not able to rightly apprehend" (Charles Babbage, 1864).
