It's a mental thing though. You don't want to be the bloke who f**ks it. Lord knows I've been there, and under a shitload less pressure than these guys too.
There is no way BA is coaching them that way, you can see it for example in the start against Newcastle, or Souths. Or even St George. We are much more expansive when we start fast or when we do get momentum (eg Manly game). The problem comes later, when the players start to tire or the opposition starts to get back in the game. Their first thought is "come on, don't blow this."
But of course that often leads to a decline in the danger levels of your attack and you blow it anyway. See the 2018 Parramatta Eels.
I do wonder, though, when the pressure will be off in their minds. Realistically you're right in that who cares if we lose throwing the footy around as opposed to losing playing safe? These guys aren't set up to think that way, though, as professionals.
