1)
the filter is a metal mesh type. if this filter is blocked, engine gets less oil or -in the worst case- almost nothing. but it's very unlikley that this filter gets blocked unless you throw something inside the tank. it is there to catch small parts which might have entered the tank when refilling oil.
to check the filter it is helpful to unlock the two bolts which fix the tank to the frame. when reinstalling the bolts, degrease first and use a drop of blue loctite to secure against loosing.
2)
this small amount of 'old' oil will stay inside the engine because it cannot pass through the oil pump and oil filter resp.
you can assume that about 0.4 l of the old oil will stay inside the engine because it is captured behind corners, in pockets / bearings
3)
the scavenge circuit brings back the 'used' oil from the bottom of the crankcase to the oil tank (via oil cooler on teneres).
the feeding circuit delivers 'fresh / cold' oil from the tank to the greasing points. remember that the task of the oil is not only greasing, but also inner cooling of the engine.
here you will find everything about the oil circuit:
