They probably mean that it is verified with human provided guides.

A human must annotate the library with carefully chosen asserts 
that the verifier will prove one-by-one until they can all be 
disposed of. So you have to understand that verification engine 
and carefully "nudge" it until it succeeds.

So, mostly suitable for the standard library and simple third 
party libraries, but not for bleeding-edge applications that keep 
changing...
