I don't believe that I ever said that SW is 'not a real airline' but their business model differs from legacy carriers, and that makes it more difficult for them to recover at times. Factor in the lower cancellation and overbooking rates for SW, and it can be difficult to standby for a flight.
I suspect that the OP's colleague decided not to go with the standby option (either due to lack of knowledge on her part, or lack of desire to go the airport daily and standby) If she didn't have a burning need to get home, I can see where taking the confirmed seat was an option for her even if it was days later.
