Meteor - Template.currentData() not reactive?

In one of my templates I use autorun to change some DOM elements when the data context changes, but it never gets triggered.

Template.onRendered(function () {
  this.autorun(function () {
    var someData = Template.currentData().someData;
    // some DOM manipulation
  }
}

The documentation states that Template.currentData():

Establishes a reactive dependency on the result.

So if someData is being changed, it should trigger a recomputation, shouldn't it?

After doing some research and getting a better understanding of reactive data sources and reactive computations and the underlying Tracker and Autorun I figured out, that I just needed to change

var someData = Template.currentData().someData;

to

var currentData = Template.currentData();
var someData = currentData.someData;

So it seems that only Template.currentData() is a reactive data source, but the properties of the object it returns are not.

One could probably change that using reactive-var.
