At the time this paper was written (35 years ago!) the discussion was about replacing the use of goto's with structured loops, if-statements, etc. Programming constructs that we take for granted today, such as while-loops, were still fairly new at the time.

As I see it, they are very similar in the way they operate. When I write subfunction() in the middel of my code, the interpreter jumps to the label(function definition) and continues, until it reaches the end, and jumps back to the original point of execution. The only real difference is that function calls and definitions are a bit more structured than goto statements, and ofcause allow scoping of variables. I can't easily come up with an example of code that could be written with goto, but not using subfunctions. What is the big difference between goto structuring and functions?
