Eventually your PR restored, good luck.
It was not a misunderstanding. The rules call for meeting the residency obligation in any rolling 5 year period. That means he can not just say that he was in Canada for 730 days in his first 5 years as a PR and then stay away for years and keep referring to those 730 days. CIC was justified in refusing him and I assume he only won his appeal because he still meets the definition of a dependent child and because his family lives in Canada.
