Very good explanation, a whole lot of people do not understand that the rod displaces fluid and if both outlets of cyl are sealed, weather it is the valve or couplers, that fluid has no place to go and cyl does not move. Also, the pressure on both side in cyl greatly increases and will cause a valve to leak that will hold normal pressures ok. I have unhooked know bad cylinders and allowed them to sit with a load on them just to prove to people they will not go down if you have both ends plugged. Often it is easy to tell if a cyl is at fault just by raising the load a little, then feeling of the couplers when they are still hooked up. The load holding coupler will and should be under pressure and tight in mating coupler and the return side coupler should be free. If the cyls are such that they hold a load up on an extending rod situation like a lot of bucket cyls on loaders then different rules apply.
