Why does GiB play this sequence as GF?

I thought this was basically universally played as F1 (apart from a handful of dinosaurs who still play NF) - GF seems almost unplayable. Judging by this hand even the robot seems confused - do they really think this is a full GF rather than, say a 2N rebid? (which already seems optimistic)

Fred once said that this sequence should be GF - the reasoning is similar to why FSF should be GF.

But yes, it is not everybody's choice.

Does this imply that what GiB plays is what Fred preferred it to play, at the time?
That would be no surprise or scandal, just curious to know.

I would assume that this is the way GIB was programmed when BBO bought it. From what I have read in these forums, GIB was not designed to make quick, simple (bidding or play) changes, not that changing 2 to game forcing from whatever meaning it might have had is necessarily easy.

No it doesn't imply that, GIBerish is probably not Fred's favourite system anyway. It's possible that GIB always played that way. I don't know.

I remember reading that the original program by Ginsberg was significantly configurable, and it seems rather unlikely to me that the current set of agreements was the default. Presumably somebody configured (or hacked) it to play this way, my curiosity is just who and whether it was already playing this way when BBO acquired it.
