I don't understand, please provide more details.
This is an ArrayNest, right?

[ARRAY-ATTR]
  [ENTRY]
    [MEMBER1]
    [MEMBER2]
  [ENTRY]
    [MEMBER1]
    [MEMBER2]

Which level are you saying doesn't matter?
If entry is a nest it must be a valid nest.
What the comment you're quoting is saying is that the nla_type of ENTRY
doesn't matter.
