It's even sneakier than that at Reno. The airport layout is conducive to light airplanes being well below the approach path of the airliners on the parallel runway.
The centerlines of the two runways are 800' apart. The north ends of the runways are even with each other, and while 16L (the general aviation runway) has no displaced threshhold, the threshhold of 16R (the air carrier runway) is displaced 1,000'. And there is frequently a crosswind from the west, which would tend to drift the airliners' wake turbulence toward 16L.
You need to stay above the approach path of the heavy, at least until it touches down. 16L is 9,000' long, which gives you a lot of room, even in the high D.A. environment. But when the heavy is overtaking you from behind, it can be difficult to to gauge the relative approach paths.
