I think you are mixing up usages 1 and 2 or something.

My reading of RFC 6698:
Usage 0: Validate up but excluding RP trust anchor[1].
Usage 1: Validate up but excluding RP trust anchor[1].
Usage 2: Validate up but excluding DANE trust anchor.
Usage 3: Validate none.[2]


[1] If DANE pinned certificate is below RP trust anchor,
DANE checks can't pass (can't happen for usage 1 anyway,
since nothing is below EE).

[2] This is actually a special case of validate up but
excluding DANE trust anchor.
