If you both are talking about James Howells who allegedly lost 8,000 BTC in a hard drive he threw away, I found no reliable source saying he found the hard drive
No idea who it was nor the name "James Howells" until you dug it up and posted it
Not sure why you assume it was "after", if he had any BTC the belongs to the PKs he owns, he would have gotten the same amount in all the forks, so if he threw it when it had BTC in it before the fork date then it would have both BTC and the other forks, if the BTC was funded after the fork, he would found only BTC, the only way he would only find forked coins and not BTC is if he funded the wallet after the fork, and lost it after the fork, which doesn't make sense at all.
We could be talking about different folks here, but James Howells claims he lost his hard drive back in 2013, which means if he found it recently, it would have 8k of BTC and every other fork.

The twit post being incorrect may well be the case, but what I stated was: apparently.
