Coincidence, homage, or knock-off?

I was listening to previews of music on iTunes last night and came across the new album Asleep at Heaven's Gate by Rogue Wave. On that album is a song called Christians in Black, which contains a little guitar bit that sounds exactly like one in the song Sacrificial Bonfire by XTC from their 1986 album Skylarking.

I suppose it's possible they came up with it independently, but that seems unlikely. That leaves the other possibilities... it was a deliberate nod, an homage, a tip of the hat or ... just a plain old rip off. Time will tell.

(Note: the links on the song titles go directly to each song in the iTunes store. Listen for yourself.)
