i'm not sure to understand

do you said that if i type
port upgrade installed and name:thisportdoesnotexist
it gives
Error: No ports matched the given expression
(like "port -u upgrade outdated"), and that it's true ?

"installed and name:thisportdoesnotexist" is a valid expression which  
results in no port,
so i expect that port upgrade understand that it has no port to  
upgrade this time, but not give an error code
i find that there is no good reason to not give an error code, since  
the given expression is valid ...

do you mean that i should do
port outdated && port -u upgrade outdated || exit "$?"
?

it doesn't works, because port outdated doesn't give an error code

moreover,
$ port installed and name:thisportdoesnotexist && echo n
+ port installed and name:thisportdoesnotexist
None of the specified ports are installed.
+ echo n
n
