You are correct, if they stopped the rear cam bearing flush with the block I could see the groove being exposed. It would be rare, but I could see it happening.
But i would think soon as you installed the cam and the rear journal dissappeared into the bearing it would be a big red flag.
I guess some assemblers just don't look for stuff like that.
Plus i don't think that issue would change with oil temp. If that rear groove was out the pressure should be low all the time not just at temp.
