It's not so strange when you consider that Southwest only began service to LGA in June of 2009 with 8 flights a day, which has just recently increased to 19.
Been at SWA for 16 years now. I've flown into and out of LGA exactly once, EWR twice, RSW zero, ECP zero, EYW zero, and SJU zero. Conversely, I could land in MCI in my sleep.
In other words, it's very possible that the accident crew would be unfamiliar with LGA.
Well, that sure explains it. Welcome to LGA! It always seemed like you guys were everywhere
