No you're right. But you don't have to worry about it. It's rather a good news in fact, I hope it will be enforced heavily.

The idea is that you can be taxed ONLY if you sell the result of the fork. If there is a fork and you don't do anything with the coins then nothing is taxable.

How is it a good news? Well it decreases the incentive of a fork. Because tons of people won't get the new coins, knowing they will be taxed.

Hence less shitcoins and less forks.
