Actually, the "robosigners" were humans who would sign (and were encouraged / forced to sign) documents asserting facts for which there was no supporting evidence, or even where there was directly contradictory evidence. Signatures were by humans, not computers.
You're right, although in practice it was largely the same thing. Huge database contains home listings, computer spits out which are due for foreclosure, a bunch of ex-fast-fooders sign them as quickly as possible. There was a human in the loop but 0% of their judgement was employed - their job was to sign stuff, and that's what they did.
