It means tha plane required 395m roll for landing and 600m distance for takeoff, which distance also includes the space required to climb to 20 m altitude (trees/buildings next to the runway!). I am not sure wheter the descent is included in the 395m landing distance though...
Also, keep in mind that these values usually refer to "normally braked" aircraft on the landing run, and takeoff on Kampleistung ( 30 min power limit ), which is a considerably lower power than full power. (IIRC ~1450 HP vs. 1800/2100HP on FW 190A).
