Yep. And if the N2 pressure in your tissues is the same as it is on the surface, how likely is it that you'll bubble if you suddenly find yourself at the surface? There just isn't any driving force pushing the N2 out of solution. And if your N2 pressure after the dive is the same as if you'd canceled the dive and had a beer on the boat instead, how likely is it that you'll bubble during a flight?
I don't know how likely. But you don't either. There may well be no clinical risk, but you should understand why, and it's not just because of what you describe.
The point of thought experiments like this are to get us to work through the basic science of diving and come to a better understanding underlying mechanisms. It’s not really about whether an actual diver can fly or not.
There are three levels of understanding in answering this question, resulting in three answers.
1) No, the diver shouldn’t fly, because all of the agencies say that you should wait 17-24 hours to fly after diving.
2) Aha! The OP has described a dive where the PPN2 of the breathing gas is about the same (or even a bit lower) than the PPN2 in the atmosphere at surface level. PPN2 gradients are what cause DCS, and since there is no gradient, there CAN be no DCS. There is no physical process to cause bubbling.
3) Wait a minute. Since during ascent there is a drop in ambient pressure, and since the diver is not breathing 100% O2, that means that there is some inert gas in the tissue, and some bubbles will form (as evidenced by experimental doppler data). Those bubbles are probably silent, meaning that the diver is at no risk of DCS when they surface, but there is no consensus on the limited (military) data about what happens when you take a subject with subclinical bubbles and then immediately expose them to a second drop in ambient pressure (air travel). My gut feeling tells me that there probably isn’t much of a risk, but it’s just that, a gut feeling based on no actual data. But I do understand that there is a physical process that can cause bubbling even though there is no difference in N2 loading between this diver and someone who played tennis that afternoon. The difference is that the diver was exposed to an ambient pressure drop.
