Two slides moving at the same time is unusual. Typically they will move one at a time beginning with the slide with the least resistance (typically the lightest), then the next least, until all are extended or retracted. The pump can only produce a certain amount of fluid flow. And if that fluid flow is shared between two slides at the same time, they will both move slower than if only one were moving.

It would not be hurting anything working as they are. But it would not damage anything to do it as you mentioned. That doesn't add more power as such, just directs all the fluid to that slide rather than sharing it.
