Thanks for tips. I was not expected that the brief second run was as designed but it makes sense.

Actually it was during this short, second pump run when CEL was occasionally triggered (P0410 and P1411 if I remember...) and I was planning to go through SAI system, hopefully to fix a simple vacuum leakage. I was wondering if malfunction of some components are making the pump run erratically, but gladly it seems not to be the case.
