No prostate biopsy can detect metastatic disease. However, based with other factors, a doctor might quote the odds of finding mets - this is a guess based on the doc's experience and biases.
Do you know what his PSA was?
A met can only be diagnosed by finding it on a scan and doing a needle biopsy.
Normally, assuming the PSA is relatively low, we start with the assumption that the PC is localized and treat accordingly. Then if local treatment fails, we know the disease is metastatic. This is why in advanced cases, scans are done to see if there are mets or not.
So yes, he needs scans, but the bad thing is that just because the scans don't find them, it doesn't mean they aren't there - they just can't be found at the moment.
But to say that, 'based on the biopsy alone' is a bit misleading.
