That is interesting and somewhat old school thinking. True there is some compaction from grazing but if there is enough plant matter and soil activity it overcomes it. Plus grazing processes the plant matter to break it down quicker and have nutrients available. the thing you cannot do is overgraze because you need the plant matter mulch as well. There needs to be a lot of plant matter left on top.Grazing is highly discouraged here because of soil compaction.
There is substantial research data that shows an improvement in soil health from grazing but to date I do not think the exact reason has been determined. Some of the theories are having some preprocessed nutrients available and the effect of the bovine digestive system for adding certain enzymes into the soil structure that helps to break down plant matter and encourage soil activity. Some data I have seen tends to lead to the urine being a critical part of the system possibly because of the enzymes - but haying and hauling manure back out is not as good as grazing for soil health. (I reference Dr. Beck for most of this information.)
