re: Plumber baws: diy double vanity question

I have a double sink in my kitchen and below one sink, the drain tees off to the other sink...below the tee, there is a single pee trap and then into the exit drain.

Not a plumber but this is how I've seen every double sink done.

One P trap coming out the wall and the sinks tie together with a Tee going into the single P trap.
