Yes, two stage triggers function just like stock AR triggers. There's a little take up and then not much more fires it. Developing a straight pull technique is a good idea to me and just be slowed down for precision fire.
The sear locations are very different on single stage and two stage triggers.

The standard AR15 trigger is a single stage trigger. The sear angle may make it feel similar to a two stage on some of them, you feel a increase in pull just before it breaks. I've modified dozens of single stage triggers like this with a simple change of sear angle.

On a two stage you well feel the first stage travel come to a hard stop when the hammer hook contacts the disco. Then you need additional pressure to overcome the disco spring for the second stage to break. A typical two stage in service rifle comp well have 3lbs+/- on the first stage, with 1.5+/- additional on the second stage. To your finger and brain this feels light a 1.5 trigger.

When you reach the hard stop of the first stage there should be zero creep from this point. Pull the additional weight and the trigger breaks with out any additional movement.
