It's not incorrect. The fact that Go players have gotten stronger over 300 years of recorded data does not in any way show that AlphaGo has made players better.

It's not incorrect. The fact that Go players have gotten stronger over 300 years of recorded data does not in any way show that AlphaGo has made players better. The fact that players are suddenly memorizing AI moves in 2016 and beyond also does not mean they're getting better. This system does not measure how good the players are. It measures how much they copy AI moves (which is rather convenient, since the article is written by AI researchers). The phrase you quoted is so hilariously worded that I initially thought it might be satire. Indeed it does "reinforce the belief" that AI has boosted the skills of players - apparently the researchers themselves are not immune to this "reinforcement of belief"!
