I cannot see Ver allowing BCH to just fade away but he will probably make a very big success of the exchange because of the bitcoin.com domain
I think so too. If you look at how much work and money he put into promotion and adoption, he surely is convinced that it will succeed. It's not a get rich quick thingy for him because it made him lose more than he gained.
He must have been a very large buyer when the ratio was still between 0.10-0.20BTC. It's not fiat he used for that, but his precious Bitcoins. He burned himself because of his believe in payments being the most important aspect.
This exchange is his last weapon in terms of pumping life back into Bcash. If this fails then he has done everything he could to try make it work, but there simply doesn't seem to be any demand for payments.
Whether he bought any BCH or not is not that important because (like other Bitcoin holders) he would have received an equal amount of BCH when the fork was created and he would have had thousands of them.
It has to be said that BCH is still a top 5 crypto by market capital and cannot be written off even though it is clear Ver lost the battle in trying to make BCH supreme over Bitcoin. If utilised properly BCH does have a future but Ver is obsessed with trying to pass off BCH as the 'real' Bitcoin.
If Ver changes direction and lets BCH develop its own path without trying to claim BCH is Bitcoin then BCH will probably be around much longer than if he keeps up the confusion.
Will Ver accept he failed in the attempt to dethrone Bitcoin?
