No, I think they mean literally. If the ingredient says "meat and bone meal" that is not good. But a named meat meal IS good. It says what animal it came from.
And a named meat source meal will account for a higher percentage of good from the named meat than a fresh meat will. Percentages are by weight. So if the first ingredient listed is chicken any good from the chicken will fall to a lower place in the list when the water is removed, which of course it is when the kibble is cooked. A first ingredient saying chicken meal will stay higher because it already has much water removed.
I like this website for information on how to read dog food labels. http://www.dogfoodproject.com/
