You made me look. My dropdown box included a domain that I abandoned in 2005 and, upon refresh, it vanished :/
To my knowledge nobody has ever picked up this domain after me, it's not currently registered, but could the data be a list of domains that at one time belonged to the same owner as other sites you have verified?
Weird, but not entirely useful. Ah well.
