That is because struts have specific mounting locations to each corner that cater to the bolts connecting to the knuckle, brake lines, and also sway bar mounting points if the manufacturer uses the strut to mount the end-link for the sway bar.
What you are thinking of would be classic of a B14 or other beam based car with struts in the front and shocks in the rear. Shocks are typically the same left and right but struts cannot be.
Google difference between shocks and struts if you want to learn more.
