Is it correct that miles and segments flown on Cathay Pacific and other Oneworld partners flights do not count towards to EQMs and EQS under this promotion even if the entire EQD is spent on AA, BA, JL and Finnar?

I may be able to spend and meet the EQD requirements by interim deadline but not EQM and EQS if other Oneworld flights are not counted.

Can someone confirm the above is correct?
