wp_reset_postdata()

I'm following along with Zac in "How to Build a WordPress Theme" and I'm getting confused in the section on "Extending WordPress Template Functionality". After he talks about wp_reset_postdata(), he doesn't seem to ever use it, even when there are multiple loops in a template. I even searched through the code files he posted and couldn't find it.

After reading [http://codex.wordpress.org/Function_Reference/wp_reset_postdata] it looks like you only need it when you go back to a previous loop, like in a nested loop. Am I understanding that correctly? Zac's code works fine without it, but I want to make sure I understand when I would need it.

Hey Adam, yeah I realized this way after recording. Technically you're right, although sometimes funky stuff comes up and it is helpful to use. Had to make a call not to go re-record this because I would then need to re-record all the code following it :-/ Sorry for the inconvenience here!

This confused me too for a while. Helpful that the project files do include the reset_postdata. Just wanted to say how helpful I find your videos Zac! Rob.
