If that comment meets the bar for "explicitly calling for violence", tens of Hackernews posters would be getting arrested daily for how they talk about billionaires. AOC should avoid travel to the UK because her "eat the rich" rhetoric is an explicit call for violence under this standard. Etc etc.
No, what they've done is create a low and unclear bar for what constitutes criminal speech, which allows the police and judges to apply the law selectively. So yeah maybe technically it's illegal but you won't get arrested for saying "eat the rich".
