crease angle: smaller instead of larger?

[rogue]

I've just downloaded the trial. Here's a quote from the manual:

The angle between adjacent surfaces is measured and if this is larger than the crease angle the surfaces will be smoothed.

Shouldn't it be "smaller" instead of "larger"? It goes on to say that a value of 0 would "force all surfaces to be flat", i.e., would produce NO smoothing. But if angles _larger_ than 0 should be smoothed, it should smooth everything.
