Well, everything in GURPS is Bungie-approved, and Bungie did look through it to check for any inaccuracies. The only really significant mistake that got through is that it refers to the Deciever in the present tense, and some people have come to the conclusion that this shows that absolutely everything in GURPS is complete falsehood (okay, that's an exaggeration, but it's not too far off).
And it's not really suprising that Bheil isn't stated as not being Bahl'al in the Myth games and manuals, seeing as she isn't even mentioned in the Myth games and manuals, other than that it is stated that there were six Fallen Lords and we've only met four of them. I suspect that in GURPS she's largely intended as a possible villain for a post Soulblighter campaign, or for a campaign in the TFL era set wherever her army was at that time (ie. decided by the GM).
