Hello Wagner,
IT Pro TV is my 2nd source for ITIL Foudnations training and I had the same reaction you are expressing here at that point in the Service Design video. In my other training Service Portfolio included everything in the service pipeline, i.e. planned services, existing services and retired services. Whereas Service Catalogue only included existing services.
When I did a search to check which training was correct I came upon your same findings also.
I believe Don did swap them when he was doing the Service Design videos.
