VoiceXML implied exiting

I'm working on a VoiceXML test suite and having difficulty understanding the 
meaning of part of the 2.0 spec... states:
	"If no guard condition is false, and the last iteration completed the form
	 without encountering an explicit transfer of control, the FIA does an
	 implicit <exit> operation (similarly, if execution proceeds outside of a
	 form, such as when an error is generated outside of a form, and there is no
	 explicit transfer of control, the interpreter will perform an implicit
	 <exit> operation)."

My question(s) are:
1. *How* does execution proceed outside of a form? All executable blocks are
   inherently within form scopes.
1a. <catch> blocks which are defined outside of a form? These are supposed to
    execute within the form's scope, but is closure different?
1b. <link>s with erroneous *expr attributes. While the <link> itself executes
    within the scope of the form it is called from, should an error evaluating
    the expression attributes trigger this?

Clarification of these points would be well appreciated.
