This is a nice example: the 2nd OPENJSON down below gets its WITH clause completely trimmed away, because it's only used for COUNT(*). But its argument referenced [o].[OwnedCollectionBranch], which makes it get preserved here on the 1st OPENJSON, as the only one.

I can inline and qualify with SqlServerOpenJsonExpression.ColumnInfos if you think that's better..
