Sure. I can interpret "close to the top of the domain tree" in two ways : content-wise (zones) or container-wise (servers). Content-wise, a recursive DNS server is neither close to nor far away from the top of the domain tree, as it is outside the tree. Only authoritative DNS servers are inside the tree. Container-wise, the DNS root servers are spread all over the internet. Besides, being close to a root server does not help much : the root servers only serve the root zone, i.e. the list of names and addresses of authoritative DNS servers for all top level domains. Top level domains and all subdomains are served by a multitude of other authoritative DNS servers, and you cannot possibly be close to all of them.
