The direct flight, DL 2551, shouldn't receive credit for two segments.
If the two trips are for business, the OP should consider the wisdom of doing wacky connections, especially on the outbound, although perhaps an argument could be made for doing this to obtain a lower fare. What if IROPs happen and the OP misses an important meeting or other business obligation?
IMO it would be better to find a separate cheap segment run to get the additional DL credits.
