In your example, you are assuming that the 1,000 people that obtain a fast pass would not ride the attraction at all if there were no fast passes available. I think that these people would actually get in the stand-by line if no fast passes were available
It really doesn't matter either way. With Fast Pass, the standby line has to move slower than it would otherwise regardless of how many people are actually in that standby line. You can have a standby line of 50 people or 5,000 - makes no difference - both (example) standby lines will still move slower than if FastPass did not exist. Continuing the same example, you have an attraction which loads 2,000 people per hour (pph), with 3,000 persons in the standby line and 500 others returning each hour with FastPass. Hence, every hour the attraction is open (except the first hour after opening*) 500 guests will be loaded from the FP line and 1,500 from the standby line - the standby line is moving at a rate of 1,500 pph (the FP line continuously empties). So, the 3,000th person in line when you start timing should reach the ride vehicles in about two hours (500 more FP holders will return that second hour), at which point 4,000 guests will have experienced the attraction (3,000 standby, 1,000 Fast Pass).
But suppose Fast Pass didn't exist, and you have everyone in the same line. Assuming the exact same number of people ride the attraction with or without Fast Pass (and we really can't just make that assumption, except for the sake of simplicity), you now have 4,000 people in the standby line, but the line will now move at a rate of 2,000 pph (instead of 1,500 pph with Fast Pass). In two hours time, 4,000 people from the standby line can cycle through the queue as opposed to only 3,000 from standby when Fast Pass is in use.
As Matt noted, in an ideal situation with FastPass the standby line may be shorter, but since it will move slower, the actual wait time could be identical. As a practical matter, though, it may not work quite so simply. Without Fast Pass, the longer standby lines discourage some people from getting in line for the attraction. With Fast Pass, the standby lines are shorter, which may tend to encourage more people to get in line (so you end up with a greater total number of people - FP + Standby - in line for a given attraction). Obviously, with a longer line the wait is going to be greater, but we still have Fast Pass going too, so the line is not only longer it is also moving slower than without Fast Pass.
Also, and as YoHo stated, we are greatly simplifying a complex set of variables. Indeed, all of our examples are probably oversimplified to a fault, with highly questionable assumptions and holes in our logic big enough to drive a battleship through. Still, the basic point seems valid, that you cannot pause loading one group of people (standby queue), to give priority to another group (FP), without delaying those who have to stop and wait (standby line, while the FP returnees board).
