No events are being emitted in sync1().
It is worst than you think, the real thing is:
var list = [1,2,3];
object.on('event', f1);
function f1() {
list.forEach(function(item) {
if (item == 1) console.log('before')
sync1(); // item is not being modified anywhere
if (item == 1) console.log('after') // this SOMETIMES gets called!!!
});
}
