How can a cockup in his area be somehow not his responsibility? For any possible contributing cause - number and expertise people working on the product, handling of acquisitions in the sector, strategic deals with other companies and partners involved, the marketing-built expectations of consumers, the PR followup of the maps - as a senior VP, it is his direct duty to make sure that stuff there happens in a favorable way and take responsibility for whatever happened.

Even if a major reason is disagreements with CEO or board or other VP's - it is still clearly his responsibility to solve those disagreements and ensure that they don't harm results. As in the Jobs' citation, somewhere between the janitor and his position that ceases to be a valid excuse.
