I agree with your observations. However, it is not necessary to try to 
second-guess WWWD to back these up. Instead, consider WDWD (What Did Wirth

Do).

1. In the function examples in the Pascal User Manual and Re****t, local 
variables are used, even when strictly unnecessary, and assigned to the 
function result immediately prior to termination.

2. In subsequent languages (e.g. Modula-2, Oberon-2 etc.) Wirth removed
any 
doubt by introducing the RETURN statement as the method of simultaneously 
assigning the function result and terminating the function.
