I am asking from a "more secure" perspective. I can imagine a scenario with two required private keys needed for decryption scenarios that may make this an attractive model. This is to settle an argument. My vote is that it is not adding any additional security other than having to compromise two different private keys. I think that if it was any more secure than encrypting it one million times would be the best way to secure informaiton and I don't buy it. So I guess my question becomes is a two locking mechanism equivalent to another one locking mechanism with a single key?

Update: Forgive me if the answer is obvious but my bread goes dead as I read books on the topic.
