The paper is available here: http://www.icst.net/research/publications/single-view/?tx_ttnews%5Btt_news%5D=165&tx_ttnews%5BbackPid%5D=77&cHash=01fce057e7ac12d78732aaf27f0a2193 AEP do in-phase decoding, and due to some math magic this enables one to dynamically change the encoding order for sources, also permitting decimal orders like 4.36. Furthermore the paper show that fewer speakers are required per order. So, a ring with 20 speakers is able to reproduce up to approx. 60th order. As the direction of the source will get more and more directional with increasing order, this can be thought of as pen size in e.g. photoshop: You can decide to have a source encoded using a low order (diffuse location) and then dynamically increase the order making the direction of the source increasingly articulated. The artistic potential of this is fairly attractive.
