it seems to be loaded towards early losses and then chasing much-needed bigger wins to recover.
That would imply that the slots have some sort of memory. They honestly don't need to do that, they just have to make sure that the RTP is spread the "correct" way. NetEnt has mastered that part in the last year or so; it's like world class mathematicians worked together and came back with the "perfect" paytables after a couple of months.
Their slogan should be "who needs to win when you can have a good time?".
NetEnt must be a real money printing machine for those running multi-platforms casinos. I'd be very interested to see the numbers.
