No, not so fancy (do they arise from interference from the internal reflections?).
In standard tunnelling, one starts with a normal oscillation, goes to evanescence in the "tunnelling" regime, and then continues with oscillation again once on the low side of the potential; in double descent the test error goes way up (like the potential earlier) in the "tunnelling" regime, and then on the far side comes back down and then continues descending.

Have I explicated my model?
Why say "bandgap" when you mean "potential wall" :)
So test-error is sampling a (thermodynamic) potential?
I don't think really so; just riffing off a similar "surfer dives under a wave" pattern — but if you could make it work I'm all ears!
None of "confinement", "energy", or "level" work in my take on "ELI5"; that is why :)
(when I have more time should I try an eight part 文 in words like this?)
