What is the difference betweens the Rogue Talent Lethal Acrobatics and the “Scout” Rogue Archetype’s Scout’s Charge?

Lethal Acrobatics (Ex): When a rogue with this talent successfully uses Acrobatics to move through an opponent’s square without provoking an attack of opportunity, that opponent is considered flat-footed to the rogue’s next attack until the end of the rogue’s turn.

Scout’s Charge (Ex): At 4th level, whenever a scout makes a charge, her attack deals sneak attack damage as if the target were flat-footed. Foes with uncanny dodge are immune to this ability.

Aren’t these moves similar and achieve the same result or am I missing something?
