Android :: Activity Finish Method Waits To Finish?

With this sample code, the activity is told to finish, but continues execution afterwards and displays the message. I'm trying to understand why this happens. The only fix I can think of is to place 'return' after finish.

public void someMethod() {
if( valueIsTrue) {
startActivity(new Intent(this, NewActivity.class));
CurrentActitivy.this.finish();

// return; // if uncommented, Toast doesn't show
}
Toast.maketext(this, "Some message", Toast.LENGTH_SHORT).show();}
