Official EA Phishing help contradicts itself

The official Phishing help page on the EA website explicitly states that "All ea.com subdomains will lead with the subcategory, then ea.com", however the playtesting site contradicts this "ea.arcsivr.com". This makes any invite to playtest seem like a phishing attempt. I believe this should be corrected or at least specifically stated as an exception to the rule so that the website regains some legitimacy.
