Answering to your first question, you can change the player point-of-view in one of the options in the HUD. The same place where you can deactivate the Fog of Ward to be able to see all what happens.He is probably refering to where you change to the player's view and see where his camera was looking at. Example a match between Jesulin and HelpingHans. (Sry guys )
You can also rotate and move the camera pressing the Alt button by default.
Watch Jesulin's POV and you get to see where he was looking at like if he looked at his fuel point then it would also show the fuel point and just follow where Jesulin look at when he was playing. Sort of like watching youtube without internet connection.
