Netty - misleading comment

iamcurious.java

Lets consider this simple code snippet :

final EventLoopGroup group = new NioEventLoopGroup(1); 
group.execute(new Runnable()
{
    @Override
    public void run()
    {
        {
            Bootstrap b = new Bootstrap();
            b.group(group) //
                    .channel(NioSocketChannel.class)//
                    .handler(new SampleClientInitializer()); //

           b.connect("localhost", 9999);
        }
    }
});

Now, "connect" will be invoked inside eventLoop,
knowing that lets jump to first method that will be called under the hood (initAndRegister()), we can read here that:
 
// If we are here and the promise is not failed, it's one of the following cases:
// 1) If we attempted registration from the event loop, the registration has been completed at this point.
//    i.e. It's safe to attempt bind() or connect() now because the channel has been registered.

So, here method register0 (AbstractChannel.java:496) will be already invoked, and because of that channelRegistered event 
is also triggered here. But some line later we can read that 

private static void doConnect(
        final SocketAddress remoteAddress, final SocketAddress localAddress, final ChannelPromise connectPromise) {

    // This method is invoked before channelRegistered() is triggered.  Give user handlers a chance to set up
    // the pipeline in its channelRegistered() implementation.
    final Channel channel = connectPromise.channel();
    channel.eventLoop().execute(new Runnable() {
        @Override
        public void run() {
            if (localAddress == null) {
                channel.connect(remoteAddress, connectPromise);
            } else {
                channel.connect(remoteAddress, localAddress, connectPromise);
            }
            connectPromise.addListener(ChannelFutureListener.CLOSE_ON_FAILURE);
        }
    });
}
 
but it is not the case, doConnect is called after.
