the pictures make it clear. Think of 1/8th Bends and Combos which are 45 degree Wyes and 1/8th bends making quarter turns in total, instead of Sanitary tees, of which you had only one before. You won't have any Sanitary Tees after you drill through the joist and put that Wye in.
You will only have long sweeps with large radius, or 1/8 Bends, or Combos. No Sanitary Tees. You cannot use San Tees to turn waste water around a corner in the vertical plane.
Post how you connect to the stack too. You are raising the pipe a lot.
