I was reading through questions related to one of my others, and came across a gem by Slytherincess about the Fidelius charm and saw something interesting.
She mentions that Harry can see Bill Weasley's house, and that he's the Secret Keeper for the house, but I noticed something else. The quote below has emphasis mine.
‘I’ve been getting them all out of The Burrow,’ he explained. ‘Moved them to Muriel’s. The Death Eaters know Ron’s with you now, they’re bound to target the family – don’t apologise,’ he added, at the sight of Harry’s expression. ‘It was always a matter of time, Dad’s been saying so for months. We’re the biggest blood traitor family there is.’
‘How are they protected?’ asked Harry.
‘Fidelius Charm. Dad’s Secret Keeper. And we’ve done it on this cottage too; I’m Secret Keeper here.

I noticed that Bill also disclosed the location of where the rest of the Weasleys were, despite not being the Secret Keeper.
Is this a plot hole?
