Slide Operation

[Eagleback]

I do not have an issue but I was wondering how the hydraulic slide operates. I am used to my old electric slide and it was on a dinette and only went out or in. my slides on my 331rlt seem to articulate and lift first then slide in. first the kitchen on the opposite door side then the dinning on the door side. my bedroom slide is standard and only goes out or in but (1) Why do they have one switch operating both slides and (2) is there any schematic or video to show how the operation actually works because the skirting under the unit covers all of the workings. like I said I do not have any issues with the slides but it doesn't mean that I will not have one in the future.
