Is this what they call no rebound?
No, when the shock shaft extends half way after pushing it in all the way is 50% rebound. If the shaft gets sucked back in after you pull it out all the way, you don't have enough oil in the shock (you are basically creating a vacuum that pulls the shaft back in). I generally shoot for 25 - 50% rebound. The most important part is to make them as close to the same as you can.
Here's what works for me:
1) fill the shock body to the top with oil
2) move the shock shaft in and out (with the cap and bladder off) several times. This will cause the trapped air under the piston to be "liberated"
3) let the shocks sit for 5 minutes to allow the air bubbles to escape (with the shock shaft fully extended)
4) place the bladder and cap on
5) bleed the shock to get the desired rebound. I loosen the cap slightly, push the shock shaft in slowly (forcing some oil out), then tighten the cap. Repeat until you get the right rebound, and no shock shaft sucking back in.
