Two text animators or an animated mask. This is pretty basic stuff. Before I type out an explanation that you can't use please give us some idea of your experience level? To duplicate this project you need to know how to add a text animator, set keyframes add a mask, animate a mask or use a track matte. If any of these terms confuse you please start here: AE Basics.
You will also need to know how to orient layers in 3D space.
As I look at this animation once again all you have to do is add a text animator for position, animate y value, make the layer 3D, add a solid with a feathered mask to use as a track matte and add a few position keyframes to the track matte.
