I refereed to getting his vote during elimination ceremony, not that torture scene. Sorry if I wasn't clear enough.

As for the scene, Noah told Owen because Alejandro wasn't around and he already brought up the topic about Alejandro, which resulted in Owen's question why he doesn't trust him. Tyler and Alejandro weren't in an official alliance at that point (but soon after this scene), so he could simply not know.
