Your post provided a little more incite. In an all hydraulic slide unit (with one slide switch )the slides are all connected together. The slide with the least amount of resistance moves first (usually closest to the pump), then the next, then the next and so on.

My 4 slide unit will sometimes act differently depending how and where it is situated. This is how they usually work.

My bedroom slide always moves first until fully open, then the fireplace/tv slide moves around 1/2 way, then the stove/fridge slide starts to move and goes 1/2 way, then back to the fireplace/tv slide until it is fully open, then back to the stove/fridge slide till its fully open, then the dinning couch slide starts and continues until its fully open.

When closing, the bedroom closes first, then the tv starts to move along with the fridge slide, the tv closes first then the fridge, then the dinning starts to close.

Hope this helps you out as it is not always the same every time.
