No, they are saying that .223 is pistol ammunition. Pistol ammunition had different requirements of the metallurgy that composed "armor piercing." Meaning, as a rifle round, elite was skirting the law -- as a pistol round, they got raided by ATF Swat Team for having armor piercing handgun ammunition. The reason is the their metals structure constituted brass core, which is a no-no in handgun ammunition. Because most steel core is not fully steel i.e. SS109 .223 rounds (there is lead included) it doesn't fall under the armor piercing handgun round. So, at least for now, that round should be safe.
