Not true--we've been over this previously.
Whether a person is a native speaker is determined by the countries' official language or languages. The "seven nations" have yet to be substantiated anywhere official that I have seen, and I've been looking.
I recently sent an email to the Workforce Development Agency, hoping to eventually get a FAQ entry shown here: wda.gov.tw/en/home.jsp?pageno=201111180014
I got this answer in a few days:
I bolded the pertinent section, translated: "The language taught should be an official language of the country of the instructor's passport."
What languages are official are determined by the Foreign Ministry:

Official languages can be found here on the MOFA website:

English is shown as an official language of the Philippines.
As far as this qualification goes, I don't see any problem.
