Let's be careful here - section 5.2 discusses the generic case of "connection 
cleanup" - that includes both implicit and explicit logouts - whereas "connection 
reinstatement" is just implicit logout.

While "connection cleanup" does not require additional connection resources
in the general case, a target wanting to support connection reinstatement SHOULD
support *opening* a second connection (though it may reject the Login if it's
for a different CID).

I believe that connection reinstatement is a useful functionality that the targets 
SHOULD support, so I agree that the change suggested by David is a reasonable 
one to make in 4.3.4 which only discusses connection reinstatement.
