Can an Eidolon be the target of a Wand of True Strike used by its summoner?
Below rules show that an Eidolon can be the target of Summoner "you" spells. UMD uses the wand as if its on the spell list and wand activation uses the wording "casts a spell" when activating the wand. This would make the answer to the above question yes. Is this interpretation of the rules correct?

The summoner may cast a spell with a target of “you” on his eidolon (as a spell with a range of touch) instead of on himself. A summoner may cast spells on his eidolon even if the spells normally do not affect creatures of the eidolon’s type (outsider). Spells cast in this way must come from the summoner spell list.
Use a Wand, Staff, or Other Spell Trigger Item: Normally, to use a wand, you must have the wand's spell on your class spell list. This use of the skill allows you to use a wand as if you had a particular spell on your class spell list. Failing the roll does not expend a charge.
Activation: Wands use the spell trigger activation method, so casting a spell from a wand is usually a standard action that doesn't provoke attacks of opportunity. (If the spell being cast has a longer casting time than 1 action, however, it takes that long to cast the spell from a wand.)
