For me, commentary only makes sense out loud, and then mostly for the benefit of the listener, so it seems odd to be "saying" the same words in my head.
There is the multisensory aspect. If you go to the trouble of saying something out aloud then it's more difficult to ignore.
The Japanese bullet train drivers are a well-known example.
But 'for the benefit of others'? Motorcyclists manage perfectly well to do assessments without it.
