B777 single engine go around and TOGA switches

[FlightDetent]

The idea that a hand on non-moving levers (stuck at idle) tells you more than a hand on non-moving levers (placed in CL detent) is illogical.

And likewise is the implied suggestion the crew would had received vital information from those non-moving thrustlevers if they had a hand on them and would have reacted, the same crew who could not react to the low speed situation unfolding right in-front of them on the PFDs because it has never occured to them that low speed is no good.

Let's face it, there are real-pilots (Boeing), half-pilots (Airbus) and non-pilots. All of them make mistakes, but the outcome differs accordingly. An Airbus half-pilot does not need to have his hand on the TLs to know what the engines are doing (as you well explained already it's non-moving and the placement is not corelated to thrust under A/THR ops) since he's vitally trained by necessity to watch the N1/EPRs.

Thus an Airbus half-pilot moving to B will have no need of touching the TLs to derive information (yet again, those were not moving anyway in the Asiana case) but would know what the engines are doing or not by looking at EIS. Still, he would have the hand there anyway, a fact showing even the last sentece of the post above is incoherent.

Now, take a non-pilot from Airbus to Boeing and there's your dish as ordered. Served on a plate of autothrottle logic that apparently has more downgrading mode reversions than the Airbus FBW itself (hyperbole).
