Everyone now calls them thrust levers, the "throttle Hold" comes from the auto-throttle system mode, hydromechanical-based engines do have a throttle of sorts, the manual fuel valve...if it's a by-product, then its a good one, try retarding the thrust levers before 80kts without disconnecting the autothrottle system and see what happens, the Throttle hold mode is there specifically on take-off, and other phases of flight to allow precisely that, or during a FLCH descent to allow the pilot to increase the thrust as desired to lessen the rate of descent, while at the same time the auto throttle system remains available to revert to speed mode when level-off is achieved...
Now....what your airline's callout when the FMA displays this mode may vary, the actual mode is "throttle hold" as this is precisely what has happened, the clutches have been de-energized to allow manual adjustment if desired, but the auto throttle system remains active to revert to the appropriate mode when needed, (climb after take-off, speed, when level off happens after a descent)
