It does not work like this. What this rule apply is that you have to have all the segments that you are flying open for an upgrade.
I have fly on upgrades from FRA to MAD and the same fly from MAD to SCL is sold full in J. If i have ask for a FRA SCL upgrade i will be deniend
This rule is use in this example if you fly the LA600 SCL-LIM-LAX all the way, and all J is sold from SCL to LIM you can not get an upgrade from LIM to LAX even if J is empty
