[NANOG] question about peering relationships

["Sriram, Kotikalapudi (Fed) via NANOG" <nanog () lists nanog org>]

Does the following ever happen in reality? Do you think it is strange and unlikely?

The lateral (i.e., non-transit) peer of an AS is also the transit provider of the AS's transit provider.  Example: AS A 
has AS B as a transit provider and AS C as a lateral peer, and AS C is a transit provider of AS B.

Thank you.

Sriram
