You have interpreted it correctly. You have a first series pass in the CPL and a second series pass in the IR.
Word of advice; if asked then inform anyone who asks that this is the case. There is truth to the fact that little weight is placed on the series of pass that you achieved after a skills test. If a potential employer is interested then they will be able to judge your abilities during an assessment. What will irk anyone is dishonesty. It has led to termination of employment and gives leverage to any operator should they decide to cut their ties. Remember aviation is a global industry however it is a small industry. You don't know who is reading your application or indeed who may have access to your personal records once you are employed!
