That is not actually true. Ability power is factored into certain ability scalings, some of which may include it as part of their damage. Garen is one of the few champions in the game with no AP scalings: his ult deals magic damage, but does not scale with AP, so ability power on him is useless. The only way you could amplify the magic damage on his ultimate (aside from bringing enemies at lower health) would be to build magic penetration or magic resist reduction.
