Okay you didn't get the memo. here's an explanation from Phil Wood & Co. (emphasis added by me)
Phil Wood offers all three tapers to try and best meet the needs of our customers who are using square-tapered bottom brackets. An explaination of the different bottom bracket tapers can be found here. In brief, most modern cranks will take the JIS (Japanese Industrial Standard) taper, in addition to Campagnolo cranks produced before 1994. After 1994, Campagnolo moved to the ISO (a.k.a. Campy) taper. The less common of the three tapers offered is the JIS low profile, which is used in some specific older-model Dura Ace cranks.

IOW, the term Campy Taper is ambiguous as it was once used to describe the pre-1994 propitiatory square taper that Campagnolo used, which has a little smaller than JIS, but closer to JIS than ISO, but was then used as an alternate to ISO when Campy switched to ISO in 1994.
