There's a LOT of very experianced keepers out there who DO advocate feeding in a seperate enclosure. Just because YOU don't(and I don't either) doesn't make it wrong. It makes it "not your opinion".
Your way is no more right, just because you state it a few times. If he gets good results by feeding his monitors in a seperate container, or by feeding his giants in a seperate container, that it works for him(and for all the other respected keepers who do so). He's not telling you that YOU have to feed in another container, so why do you feel you can say he CAN'T?
I've done both, and I can see the merit in both.
