I am a bit confused, what is the relevance of that paper to the comment? Unless I misunderstood, the comment appeared to be about flow control issues of exceptions(hidden control flow and corrupt state), and I don't see that addressed in that paper.

The paper is about subroutines (function calls) being a lot less complex because all a subroutine can do is finish and then go back to its caller. There are no semantics in subroutines for jumping around willy-nilly.
