An attempt to commence a go-around or balked landing while in the low-energy landing regime is a high-risk, undemonstrated maneuver.
Dunno what that writer's experience is, but it sounds more like a lawyer's "CYA" statement than a professional Pilot's.
We demonstrate it as part of our Cat II/III training in the simulator. Our Flight handbook allows for go-around / balked landing up to the time the reverser levers are pulled.
Again, "ground contact" is not evidence of a failed go-around or dangerous situation. It is merely the inevitable result of a late-initiated go-around.
