Although the tokens are attacking, they were never declared as attacking creatures (for the purposes of abilities that trigger whenever a creature attacks, for example).

You choose which players or planeswalkers the two tokens are attacking. They don’t have to be attacking the same player or planeswalker that Leonin Warleader is attacking, and they can each be attacking different players and/or planeswalkers.
