If RelayState is set from the IDP the SP will redirect there.
Otherwise the SP can set homeURL, see
https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPApplication#NativeSPApplication-Attributes
With both absent the user agent will end up at / on the vhost.
No idea whether that answers your question.
