R4 - Freewill

If you choose not to decide you still have made a choice.

When Permanent Waves came out, the lyrics on the album sleeve had this line printed this way:

If you choose not to decide you can't have made a choice.

I always wondered if it was intentional. Were they choosing not to make a choice between the two versions of this line, choosing NOT to decide? Was the ambiguity supposed to be part of the point? Or was it simply a misprint?
