Yes, this is a thing with older Embraer products. I did use the technique to transfer fluid, but I never, ever did it in the air because your natural muscle memory is to leave the brake handle set. My fleet had a couple parking-brake-set LDG incidents, fortunately only resulted in blown tires and flat rims.
As others said, a NSW failure would not explain the locked mains, you'd need a simultaneous anti-skid failure to account for that.
