I don't know, maybe it's a typo? You could email Bee-Line and ask, they're usually pretty responsive.
BTW, several times when working really
late, I saw that 1C-1W bus. It was strange to see the bus come south on Rt.9A and then turn west on Rt. 119. There's no stop at that corner at Elmsford Square so to transfer to the 13 you'd have to get off at the next stop on 119 (under the Saw Mill River Parkway overpass). Strange.
I could've taken it a couple times but the connection with the westbound 13 was too close -- 9:20 for the 1C/1W and 9:22 for the 13 -- and I chickened out. Believe me, after you've worked darn near fourteen hours the last
thing you want to do is miss the connection home.
