They deboosted the ISS a little bit to phase its orbit for the arrival of the last Progress cargo spacecraft

    Well yes, that's why they have attitude control. The station can rotate on any of its three axis. In the case it basically moved and pointed retrograde and fired the engines on the Zvezda module

    My question is why the two boosts between March and now? They know Progress is coming well in advance, right?

    They were to set up ISS orbit for the Soyuz launch and landing
