Certainly nothing wrong with it, but it's unusual to see opposite sex siblings sharing a room at that age, unless it's a necessity. That house looked big enough that one would expect it to have at least three bedrooms.

They were definitely too old to be sharing a room.
I thought it was much worse though that their father would let a stranger sleep in the room with them. What if he was a perv?
Their house looked big enough for each kid to have their own bedroom. I've always thought that was weird.

Is there something "else" you are really trying to ask or imply?
As a matter of fact, "Sally" was played by an actress born in 1993. With the movie released in 2003, she could have been nine years old (possibly only eight?) when the movie was made. Not even a "tween".
Actual sleeping arrangements vary widely by cultures, (and preference), and there are some well known actors in Hollywood that have their entire family sleep in one big bed. Surprised? Shocked? Don't be. My wife and I hosted several high school age foreign exchange students, (in the USA), and the exchange student program required them to have their own room, minimum of 100 square feet, and a window. (I should mention those requirements are also requirements for an adopted child (of any age) as well. Is that a "back-door" way to specify a minimum level of living standard?) One of the students came from the Philippines, and after a few weeks with us, she mentioned that her whole family slept in the same bed. Except her. She was a "very mobile child", (her own words), and at age 12 was bumping the others in the bed during the night with knees and elbows, leaving bruises and an occasional black eye. So, she got her own bed, still in the same room with the family. (She was not an only child.) Incidentally, their family was wealthy with her father having a professional career/job. Might that arrangement have been to protect their children from a possible intruder/kidnapper?
Just sayin'...
And she was a bit surprised that children in the USA not only have their own beds, but sometimes have their own rooms as well. Sometimes that applies to the parents as well. One of the things we told the students was to think "It's not good, it's not bad, it's just different" and that helped them find/explore differences while living here, and make friends.
(While not common, there have been cases of child abductions in the USA with entry to the child's room made through the room's open/unlocked window. Many/most remain unsolved.)
