What is the meaning of the Four Corners scene?

IMO, Skyler was looking for a reason to stay back. A reason not to flee from this madness. Even though probably every fiber of her being told her to do so. When the entire situation was suggesting her to make a move, she came to the Four Corners expecting the "Universe" to indicate in some manner that she should stay back with her family and not run from them.

So, she tosses the coin and lets the "Universe" decide (even though it was more like her asking fate to support her decision). But when both the tosses land up in Colarado, she steels her will and pulls the coin back to New Mexico.
