Is this how preinfusion is supposed to be on Bezzera BZ16?

Looks like it pumps a tiny bit of water, waits a split second and continues the full extraction...
In the video, i pressed the brew button and stopped it after it started the full extraction. Then i pan to the pressure gauge to show the reading when the preinfusion happens.

Do all Bezzeras do the preinfusion like this? Or do i have a faulty unit?

Here's a clearer view of pump pressure as i use a blind filter to allow the head to build pressure.

Is this normal?
