Indeed, I came across this too. My understanding is that this does not apply (and take this with a big grain of salt; I might be totally wrong) because before these rules, the spec says:
```
Certain variables and objects have predetermined data-sharing attributes for the construct in which
they are referenced. The **first matching rule** from the following list of predetermined data-sharing
attribute rules applies for variables and objects that are referenced in a construct.
```
The emphasis here is on "first matching rule". I might be reading this wrong though, hence asking @mjklemm if he has any input. If it needs to be `private`, I will work on that for sure.
