We know that they restarted a few seconds later a few seconds apart from each other, and shut off a second part from each other.

It's extremely unlikely for a pilot to decide to react by shutting both switches off, then turning them on within seconds (this is not a failure mode they'd have expected, deciding to shut the engine off a couple hundred feet in the air would be... a fairly reckless decision).

That leaves both switches spontaneously turning off, then back on, a couple seconds after takeoff, which is a failure mode that's never been seen before once let alone twice. Also the pilots didn't make a statement about an incongruity between the report from the plane's systems about the switch being off vs the physical position, which they very likely would have in such a situation.

I think it's reasonable to rule that theory out.
