No.
You provide multiple rooms. Sky stick a box in each room. They provide you with 2 cards with the same package programmed on them.
You will need one lead from the dish to each sky box, or 2 from the dish to each Sky+ box (so possibly 4 in total if you have 2 Sky+ boxes).
The Sky LNBs have 4 outputs.
Both boxes need to be connected to a phone line, which is the same number (so they can check that you didn’t move the 2nd box to a mates house). The phone lines both need to stay connected ‘permamantly’.
In reality, as long as they are connected most of the time you won’t have an issue. One of mine went duff a couple of times, and I got a nice letter asking me to fix it.
If you just wanted to watch the same channel in 2 rooms at the same time, all the sky boxes have always been able to do this – RF2 output, run a cable, etc. If you want to watch different channels in 2 rooms, then you need multiroom.
