On the Doctor Who ansible reference

I didn't catch it the first time I watched the Neil Gaiman episode, but I did catch it the second time and said something about it on Facebook. The captions actually didn't catch it. It says '-----class'. At least the ones that aired on BBCA the first time it was shown.

This month's Ansible says:

"Neil Gaiman's Doctor Who episode 'A Nightmare in Silver' (11 May) includes a dialogue homage to Ursula Le Guin, or perhaps Orson Scott Card.... About nine minutes in, a character is heard to say: 'It can't be broken – it's a solid state ansible-class communicator!' [NG]"

Does authorial intent matter here? Is it an homage to OSC if Gaiman thought it was an homage to OSC? Standing all by its lonesome, without getting into Gaiman's head (or perhaps someone else's, if he wasn't responsible for that bit of technobabble), isn't it a shout-out to Le Guin?

OSC doesn't get to claim credit for the ansible. He just doesn't. Well, and the fact is he doesn't. He's on the record somewhere or other as identifying his source.

So people don't get to claim credit on his behalf either.
