Mike,

yes, that's correct.

Section 6.3 states:
"All values are in the state undefined when processing starts." and
"A dictionary can be explicitly reset. Resetting a dictionary will set the 
state of all its entries to undefined."

Regarding a field with a copy operator, section 6.3.5 states:
"When the value is not present in the stream there are three cases depending on 
the state of the previous value:
...
- undefined – the value of the field is the initial value that also becomes the 
new previous value.
..."
