This is correct.
Mounting of the front ones is difficult. I recommend to test them under load with an external hand lever oil gun before mounting. Are they tight on the shaft, at the top and at the bottom? I had to remove mine several times before they were tight. If I remember right, you can srew a ring inside tighter or loosen it that presses the shaft seal out. If tightened to much they won't retract.
On the image you see the oil gun and pressure gauge I used. Pressure lifting the car will be around 40bar
