You certainly can have a race condition, but the more likely thing is either the network never had internet reach (walled garden) or temporarily doesn't have access to the internet. Both the cell radio and wifi have a tendency to hold on trying to get reconnected before they give up and report a disconnection.
Other than that, your code looks good. You can also cache this value and then listen for broadcasts rather than calling ConnectivityManager all the time - depends on how often you check this.
