by separating the functions of internal and external, you have one exchange installation used for handling internal messages, while the external ones get ported to the other server to free the internal one from long queues and the vagrancies of the internet.

It also allow separation from a security point of view, no need to offer OWA or Mobile connectivity internally.
No need to have Gigs of storage available externally.

For larger sites, it may be a performance issue, they may use public folders and shared calendars a lot..

some do it for demarcation, a separate group look after the DMZ services, compared to internal services..

Microsoft Exchange Server 2003 and Microsoft Exchange 2000 Server support using a server architecture that distributes server tasks among front-end and back-end servers. In this architecture, a front-end server accepts requests from clients and proxies them to the appropriate back-end server for processing.

This best for distributing your tasks effectively, more you can find from microsoft's detailed documentation on this topology.
