No, it's a difference in terminology between AA and CO. In AA speak, you only get one elite-qualifying segment per flight segment, regardless of fare class. In CO speak, these "segments" are called Elite Qualification Points which is wholly different from the AA concept of EQP. On CO, you earn 1.5 EQPs per segment flown on full fare coach (Y/B) and first/business class fares (discount coach fares earn 1 EQP per flight segment). It makes it a little easier to earn status on CO if you fly lots of short segments at high fares. It probably doesn't impact a ton of people.

The other related benefit of CO over AA is that it is a bit easier to qualify for status if you fly a mix of high fare/premium cabin travel and discount fare travel. On AA you obviously earn 1.5 EQPs per mile flown on the high fares, but that can be offset by the 0.5 EQPs you earn on the deep discount fares. On CO, you get 1.5x credit on the high fares, but never less than 1.0x credit on the cheap fares.
