I don't really see how this is relevant for the OP...
My statement is rather generic - when you have connecting flights, and first flight arrives late, bags may move not as fast as PAX.
Another important point - while officially airline may tell you that 50 min connection time is OK, inofficially you can get different "more practical" info.
ANA connecting with UA, an NRT with 1:25 connecting time - two different airlines are involved - in case of any delays could be a problem.
I also commented that in this specific case it will be probably OK.
