This is not strictly true.
Consuls from Schengen countries are required by law to automatically check the VIS database before issuing any visa. If he has two strikes against him from two different countries, one for being a security threat, and the other for entering into a sham marriage, it is exceedingly unlikely that a third request would ever be granted, especially considering his country of origin.
You do brush up against another point, though. Even if he is granted a visa, the straż graniczy can always refuse to admit him if they consider him a security risk or if they suspect shenanigans of any sort. Especially if he appears in the Interpol database or any of the anti-terrorist databases, which are automatically checked when they scan his passport. The straż graniczy is also to required to check the VIS database for each arrival (that's what the fingerprint scan is for). They are not bound to admit him just because he has a valid visa. He can also be prevented from boarding his flight to Poland in the first place, as well, if he is in the Interpol database. Passports are checked at the check-in counter and may be scanned at the security checkpoint. An Afghani passport is probably going to be scanned.
He has a really tough row to hoe.
Three red flags that he isn't telling the whole story. The first is that he says he worked five years trouble-free in Norway, but was denied another visa for being a security threat. The next is that he mentions that he is a local journalist and small business owner, ostensibly as proof that he intends to return to Afghanistan, yet he clearly states that he intends to go to Norway when he leaves Poland. The third is that he does not intend to live in Poland with his wife, again because he will be going to Norway. That just doesn't add up.
