I don't think it's paid out of the held amount:

And we don't know if the amount has been revised since then.

On the other hand, a high fee might make sense for a single holder of funds because of risks and logistical challenges (if they're serious in protecting the funds in case of an accident for example, so that might involve a living will / lawyers / etc). Some of which might not be necessary with multisig so the fee could be lower in that case.
