I haven't parsed the language, but there could be an inconsistency without an amendment. (Note that "inconsistency" is not the same as "wrong".) For example, PPA06 included language that requires plan modification in certain circumstances (such as the automatic freeze if a funding level drops below a certain level). Somewhere in the future, every plan must be amended to incorporate that concept, but we don't know yet how to do it. Thus, your plan may have that deficiency.
However, it is difficult to see how a terminated one-person plan could suffer any harm by not having the language. In 2010, when the IRS provides some guidance (ha ha), it seems unlikely they will require modification for plans that no longer exist.
But, what do I know. Discuss with your ERISA attorney?
Also note that some of the document vendors will be coming out with sample good-faith language soon. Consult with your vendor for timing.
