RFC 1930 gives guidelines on using an AS. A good current definition
of AS, which isn't necessarily the one you see in Cisco training
materials, is a set of addresses and routers, under one or more
administrations, that presents a common routing policy to the
Internet.
In your example, company X is presenting the same routing policy to 4
ISP's. It should use a single ASN.
