Here a key adverb is expurgated from the source; “Still.”

Taken in its sense of “nonetheless”, this invites us to parse the foregoing into two distinct, contrasting sections. Thereby only Code of Honour and Unexpected Success need be understood to be claimed as parallel.

Since the term parallel is itself used analogously, any type of concordance or interdispositionality might qualify. It may even suffice to assume that the author is actively asserting that asserting that having a code of honour is, in their experience, a necessary condition to unexpected success.
