How to read this ASPA check

The 2 providers below are the only networks allowed to appear directly above AS57152 in an AS-path. If AS57152 uses a transit provider that is missing from this list, routers that enforce ASPA treat its routes through that provider as invalid, so the list should include every current and backup transit provider. Peers do not belong in it.
