Does Google Affiliate Network restrict affiliates from running other affiliate networks?

An affiliate this morning informed me she could not run any outside affiliate programs or networks on her blogs she participates in Google Adsense / affiliate program and as such she is prohibited from running any other affiliate networks.

Which led me on an Internet search to verify her statement. I also asked a well known Affiliate Manager and the reply I received was ” Absolutely not true.”

It seems there is one Blog Network that restricts affiliate ad placement but Google Adsense doesn’t. Want to verify for yourself? Here are the Google Affiliate Network Terms:
