works if generator is not calling another function ?

example from http://davidwalsh.name/es6-generators-dive
similar example at https://gist.github.com/deepak/9a7337d7a641f8af9c8b

function getStockPrice() {
   seq.throw('oops! could not get stock price');
   // seq.next(80);
}

function executeTrade() {
   setTimeout(function() {
      console.log("trade done");
      seq.next(true);
   }, 300);

var flag = false;
var promise = Promise.resolve();

// not linear execution of code! 
// is the then callback pushed onto the call-stack. how ?
promise.then( (x) => {
  console.log(`flag is ${flag}`); // flag is true
})

flag = true

let pr1 = new Promise( (resolve, reject) => {
  resolve(1);
});

// ignored value.
// would have been nice of function is required to have correct arguments
// TODO: try with JSHint
pr1.then( () => {
  console.log("hello");
})
