I've been out of lessons for a couple years and am just starting back up on my own, so I've picked out a few short pieces that I like listening to personally. I don't remember learning about this kind of technicque, with the sustained notes being played again within the same measure. How am I supposed to play this?

This is my first post here, so if there's a sub better suited to these kinds of questions, kindly redirect me there.
