Please, please, please have a bile acids test done. It's not that expensive (I pay $80 for it) but it's absolutely necessary with birds because regular blood work does NOT show a change in the liver enzyme levels until the liver is only working at 25%. I learned this the hard way when a bird I had rescued died of hepatic failure after the best and most respected avian vet in my area had told me THREE times (after three blood tests because I kept on bringing him back as he did not look well to me) that there was nothing wrong with him (this bird showed normal liver enzymes on his chem pane until less than one month before dying -I did not know about the bile acids test then).
What the vet is talking about is called psychogenic polydipsia which basically means that the bird pees a lot because it drinks a lot but not because there is a physical cause for it. It's common in puppies which drink and drink without really been that thirsty and then pee all over the place and, although they say it can happen to birds, I've never seen or heard of a case (which doesn't mean it cannot happen but that it must be rare).
He doesn't have a large output of urine... or, at least, if he does, the pictures you provided do not show this and, in my personal experience (not vast as I only had two birds with this problem), when there is polyuria, there isn't a single time they poop that there is not a large urine stain (with the tiel, the paper at the bottom of the cage would show a stain the size of roughly 12 x 8 inches and go through 4 layers of it in the morning after an entire night). What the pictures do show is that his urine is not clear and that is not caused by psychogenic polydipsia, quite the contrary, the urine is just like water because it has not chance of getting 'concentrated'.
