Twisted doesn't change anything about Python in this regard. One
update to the dictionary is going to happen before the other. If these
updates are being done from different threads, you need some kind of
synchronization to make them happen in the order you want.

However, if you aren't explicitly using threads in your code, remember
that Twisted doesn't run your code outside the main thread unless you
ask it to. So nothing happens at "the same time" -- one function runs,
then the other.

What problems are you running into?
