This just indicates a failure to perform a proper Analysis/Specification/Requirements phase No, we're suggesting the analysis/specification phase should be comprised of what are, effectively, many really small waterfalls. And that any effort to obtain specs for an entire system without first building some minimal version of the system is doomed to failure. For a small enough feature, yes, you end up doing waterfall. The problem is breaking up a massive system into those small enough pieces.
