CX Magazine noted sidewall leakage from the get-go, so it wasn't going to take much sidewall flexing to open up more spots for sealant to leak out. Especially at the low pressures they were running.
Given the way the fabric is laid up, it's pretty easy to see which paths leaked sealant will take, given the chance.
I expect to see frayed ends flapping in the breeze when threads have truly broken. That's the kind of thing that should concern you and make you consider replacing the tire. Not what we've seen so far in this thread. I've had a handful of skinwall tires lose their sidewall latex and look worse than the OP's picture, but they hung on just fine until they wore out or succumbed to an unrelated injury.
That said, running really low pressures accelerates sidewall wear, so the pattern of the OP's wear indicates he should probably be running a bit more pressure.
