Not quite, its a matter of temporary object lifetime. In

foo( bar().baz() );

the object returned by bar() lives until the foo() call is completely done.
So even if baz returns some internal data of the bar-object that internal
data will live until the foo() call has completed. So with the above
there's only one pitfal: If foo() stores the internal data from baz()
itself and later on something tries to access it.
