Fine, it's a stretch. But the WAR stat is certainly not infallable, and even if Howard was to put up precisely the exact same quality year to year, his WAR would fluctuate. He'd be just as good, but would be less or more good than the replacement player. He's seemingly upped his defense, although it appears he's taking less walks this year in exchange for more singles. He's also on pace for a career low in Ks and seemingly has stopped the vs LHP dropoff, being around his career average and actually getting some power hits off them. So maybe he's not "getting better" each year, but he seems to be working hard to inprove some of the deficits in his game. He's obviously not going to be worth the contract, and I wasn't comparing him to the best players in the game, but he seems to be rounding out to be more than just a 1 dimensional slugging DH.
