Can re-entrancy occur when calling `withCheckedContinuation` in actor isolation?

Using Swift

i have some actor lifecycle logic that works like:

actor A
{
    var state:State
    var x:Int?
}

extension A
{
    func drain() async
    {
        self.x = nil
        await withCheckedContinuation
        {
            self.state = .draining($0)
        }
    }
}

but the documentation for withCheckedContinuation says:

Suspends the current task, then calls the given closure with a checked continuation for the current task.

(emphasis added)

does this mean it is possible for concurrently-executing code to observe self.x == nil, but self.state != .draining($0) in the same critical section?
