You can achieve this easily using "Track motion" for each track (on track header, far left of each track), resizing each track and moving appropriately so you can see the track below. I'm sure the manual can assist if you need more.

and recommend a third , bottom track for background, as if using both tracks and maintaining aspect ratio, you'll need a background.

You can also do it by using Pan/Crop on the individual tracks to place the video where you want it.
