This technically violates the BGP requirement that all BGP speakers in an AS be IBGP peers, it will work with one exception: you will not be able to learn routes to your other sites sharing the ASN via BGP (they will be discarded as looping routes). However, you should be able to use static routes to your ISP(s) to do the job.
The "correct" solution is to set up a VPN between your isolated sites and run your IBGP through that (you will still need static routes so that IBGP will know you use the local ISP to get to the other site). If set up correctly, this also prevents intersite traffic from traversing the Internet in the clear.
No, in fact it is just the opposite. The two sites MUST only advertise different networks (unless there is a link between them, in which case you can run IBGP between them and have a legal configuration, but that was not your question :-).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
