Is it possible for an IdP to service multiple SPs without SSO between SPs?

>>Just out of curiosity, to prevent App1 and App2 on SP1 from sharing an authentication session wouldn't it be more appropriate to define App1 and App2 as their own unique SP? If not why?

SP1 -> App1
SP2 -> App2
SP3 -> App3

For me, each SP runs on a different host.
