Relevant or not, its the first time I've heard of putting an H1 tag in the footer. Perhaps calling it an F1 tag would be more appropriate. Seriously, some would argue the H1 tag has little to no relevance (Rand would probably fall into this category) and therefore some do not use it at all. Todd Malicoat would suggest the H1 tag has some relevance and is a good practice for page structure and keyword instance.

A recent thread among these posts and one I ascribe to is that failing to use an H1 tag is probably not going to hurt you, but using one is certainly not going to hurt you. If it is going to be of benefit to the user in terms of readability and navigation (with an arguable smidgeon of G benefit) go ahead and use it.

That being said, strong keyword copy in the lower block level is good block level distribution. Putting an H1 tag would be irrelevant in my opinion and unorthodox as H1 tags historically have been in the top block.
