Object.observe - Multiple observers support?

Can someone tell me if Object.observe() will (once implemented) allow to register multiple observers via multiple calls? Or only the last one will stay?

For example if I do:

Object.observe(obj, myFirstFunction);
Object.observe(obj, mySecondFunction);

Will both functions get called when my object is updated or only mySecondFunction?

I tried this and I got that both are being called.

var obj = {name:'MD'};
var myFirstFunction = function (changes) {
    console.log("First " ,Object.keys(changes[0]))
}
var mySecondFunction = function (changes) {
    console.log("Second ",Object.keys(changes[0]))
}

Object.observe(obj, myFirstFunction);
Object.observe(obj, mySecondFunction);

obj.name = "Mritunjay"
