Not true. When auto-thrust is turned off, the engines will adjust thrust to match the two thrust level symbols (blue doughnuts). In this case, the auto thrust likely disconnected in cruise while the thrust levers were set to CLB. Without a pilot action, this would cause the thrusts to be increased to CLB to match the thrust lever symbols.
EDIT: I TAKE IT BACK, CONF iture was correct.
What I wrote is true only for voluntary Auto thrust disconnect. In case of involuntary disconnect, the thrusts are frozen at the actual power settings
