It's not. Look at 240.4(D)

Correct. 240.4(D)
I believe in the 99 NEC, this was in a note to table 310.16 (with an obelisk).

14 gage THHN is rated at 25 amps, not 15. the 25 amp rating is used for derating, some times it can be used at the 75 deg C rating of 20, often is required to be used at the 15 rating, by 240.4(D).

#14 THHN must be protected at 15 amps unless it falls under the exceptions listed in 240.4(G).
