Reading Routings from ExpertFlyer

Routing rules on expertflyer.com are often listed differently than routings found on expedia. I am familiar with how to read Expedia routings, like the ones in this thread. The routings on ExpertFlyer, however, often appear as a simple list of cities in alphabetical order. Can someone help me understand how to determine legal routings based on the expertflyer rules?

Here's an example:

AA NR3CFN fare BDL-SFO Routing from Expedia:

Code:

ROUTING    2    FROM  BDL-AA-CHI-AA-STL-AA-DFW-
             OR FROM  BDL-AA-NYC-AA-BNA-AA-DFW-
             OR FROM  BDL-AA-NYC-AA-CHI-AA-SEA-
             OR FROM  BDL-AA-NYC-AA-STL-
                  TO  AA-SNA/SEA/LAX-AA-SFO*

AA NR3CFN Routing from ExpertFlyer:

Code:

 2 BNA CHI DFW LAX NYC SEA SNA STL

Both routings list the same cities. Looking at the Expedia routing, it is not possible to route through both DFW and SEA. How can one tell this from the ExpertFlyer routing?
