They might swarm. Once the urge is initiated, it doesn’t just go away. If they are strong enough and the weather is nice they might swarm and they might not. It’s a case of trying to cover all eventualities.
I work with Apis mellifera mellifera. I don’t know anything at all about Apis cerana.

Thank you for the reply. so it means that they will swarm even if they are already queenless? Can i apply this method to apis cerana?

So that you can be sure that no virgin queen can emerge and lead a swarm before you come back in 7 days to move the hive to the other side.
If you left capped cells you don’t know when they were capped or when the virgins will emerge…
