Questions concerning Kamui's dimension

[Bogard]

During the kage summit, we know that Obito warped Sasuke and Karin in the kamui's dimension

After that, he had a fight against Fu and Torune, where he warped them in that same dimension like you can see here

Questions:

1- Since Sasuke and Karin where already in the dimension, did they met Fu and Torune at that time?

2- He said that he actually used genjutsu on them, but when? If Fu and Torune were really send at the same place where Sasuke and Karin where, they would have seen him coming and cast the genjutsu on those guys, right?

3- Fu and Torune were warped in that dimension, but they were still alive, right? So when did Obito really found the time to come and cast genjutsu on them? Why weren't they able to defend themselves since it doesn't seem that in the dimension you're movements are restricted?

4- If they didn't met, it means they where somewhere else, right? Does it means that Obito can decide where to send the people he warps in his dimension?

I think the dimension is a side step in an alternate dimensional scale so its corresponding in space to the outside world but just distorted so Fu and Torune were transported to a different spot than Sasuke and Karin because they were sent in from a different place, which is why Kakashi's Raiton Kunai still hit his mask.

This is also probably how Obito travels so fast (faster than Zetsu) is if he can travel instantly within the Kamui dimension.

Precisely as Vinnie says.
There is an unknown limit to how big Tobi's dimension is. For all we know, it could be nearly infinite in size.
Fu and Torune probably didn't encounter Sasuke and Karin and were sent to a spot much farther away from them.
Very good question Bogard.

Interesting answer but if it's really the case, how can you explain that Obito was able to teleport himself close to Sasuke and Karin while in the other dimension when he was far from the kage summit where he warped them? He didn't even teleported himself near Fu and Torune when they were in the same position. Is it possible that Obito can control where he can appear in his dimension?
