Not 100% true. (but often repeated on BITOG) And you can see this misinformation has lead the OP down the wrong path.
Amsoil has PAO's, Redline has PAO's. Amsoil has esters and Redline has esters. Depending on which oil we are talking about Redline probably does use more esters in their motor oils, but some/most are 30-40%+ PAO. Amsoil is probably higher at 50%+ PAO.
It's not misinformation, IMHO. Redline uses Polyol esters as their base stock, Amsoil uses PAO as theirs, hence RL being considered an ester oil and Amsoil a PAO. So calling RL an ester oil and Amsoil a PAO might be overly simplified, but it's essentially accurate
and not leading anyone down the "wrong path".
Sure, Amsoil contains other ingredients to compliment the PAO and RedLine uses PAO as an additive carrier (this comes straight from RL), but I'd be willing to wager their respective percentages of esters aren't even close. FWIW, I e-mailed Dave at Red Line about the respective differences between the base stocks in RL's street and race oils. Here's what he said:

Which brings me to my next question; where are you getting these percentages from? RL doesn't share this information, and I'm pretty sure Amsoil doesn't either.
