I have not installed this particular bearing, so I am not expert here, but I have installed others. Maybe, hopefully, this is helpful-
The idea is that you are squeezing the two bearing halves together to remove slop. The amount of pressure squeezing them together is the “load”. The bearing half opposite the nut must obviously be fixed or you could not load the bearing by tightening the nut and squeezing the two bearing halves together. I suspect you are thinking, duh!
The only reason I mention this is because:
"It seems like one bearing that slides on the shaft would be enough”
This is true, as long as the bearing half opposite the nut (outer half) is all the way on the shaft and is firmly seated against the shaft flange or whatever stops its movement on the shaft.
If for instance the outer bearing was difficult to slide onto the shaft and it stopped sliding on the shaft due to friction rather then pressing against a flange or whatever stops its movement, you could load the bearing by tightening the nut and think everything is OK. Over time, pressure from the nut could overcome the friction holding the outer bearing half in position on the shaft, causing the outer bearing to slide further down the shaft, away from the nut and inner bearing half, resulting in decreased load pressure between the two bearing halves, resulting in slop.
So your understanding is correct, just be sure the outer bearing is all the way on the shaft.
