There is a wall between the new / old toilet locations, so I can easily install a vent where the line runs under the wall, before it intersects the line from the washing machine. Now back to my original question, should that be a wye or a sanitary tee?

Can the two wye's install nearly back-to-back like this?

Please see attached. I am trying to put a washer in approximately the current toilet location, and move the toilet about thirty inches to the left. I'm unclear as to whether the Y fitting shown should be a "wye" or a "sanitary tee" I believe it should be a wye... just trying to double check...
