Okay, As you've taught me, I've just re-read the article more closely.

This guy isn't providing much cover to Clark is that's the intention of coming forward as he did yesterday. He says he didn't call Clark on 9/11 but rather a day or two later.
Not something either would forget.

He also says he didn't pressure Clark to make the link, only asked about the possibility. Again, something neither would forget.

So, he isn't being used as cover. Perhaps a blur for unsuspecting readers.

I think the blur is for media types to give Clark the excuse that in the confusion surrounding 9/11 no one could be expected to remember every little detail, now could they?

The problem with this entire Clark preposition is that few people have forgotten anything, including telephone calls of that day, not matter the importance. It is one of those days in our shared natinal experience that will remain in our minds in crystaline detail.
