The difference is he's at least acknowledging it now. And we don't know what the next chapter has- he might end up apologizing for all we know. But, he quite literally is changing. You can't expect anyone to change their way of behavior or reactions to certain things overnight. It's a process. Especially when it's how you were raised or shown how to go about life. He had the right footing with mentally getting on-track, but everything went downhill so quickly, people are relying on him more than ever, his career and health is quite literally on the line with this match, and the one person he started feeling comfortable with is leaving. With that stress piling on, lashing out is unfortunately a realistic outcome. That's called being human. We all experience anger and stress. If we don't have healthy techniques to relieve it, there will be unhealthy outcomes and accidents
It's not necessarily "right", but faulting him for something like this when he did remove himself from the situation knowingly is ignorant to his entire character development. If he truly meant what he said to Dan, he wouldn't have done that at all.
