The rewards are not noncustodial, the pool still tracks them and decides when and how much to pay. The only difference is the pool pays out faster/more often than many other pools. However, pools doing lightning payouts are even faster! 

 Also, it’s important to note that many miners can only handle coinbase transactions of a certain size, so there’s a very low limit on the amount they can pay out in coinbase transactions, much higher than dust. 

 "We are also the only non-custodial pool, making you, the miners, recipients of new block rewards directly from Bitcoin." 

So you are saying you believe this statement to be technically misleading? 

 Incredibly so 

 Hard to validate without viewable code.
