He mans that if you were encoding from an original lossless source ("Master"), then you would need significant more bitrate to retain all detail, because there is so much detail/grain in that source.

However we usually don't have access to such sources. What we have are BluRay's, which have already been filtered and compressed in a lossy way. Many detail is already gone for good when we get the data!

Re-encoding such lossy sources requires less bitrate to retain all details (the details that are still there) for obvious reasons...
