According to Spotrac, Green has received 18 ejections since he entered the NBA back in 2012. When it comes to the first seven ejections of his career, Green was tossed from games in which Curry was actively playing.
The first instance in which Green was ejected while Curry was inactive came on Nov. 11, 2019. Curry was dealing with a broken hand at the time. Green ended up receiving a pair of technical fouls during that contest. Ironically enough, that game came against Gobert when he was a member of the Utah Jazz.
Following that incident, Green's next four ejections came in games in which Curry wasn't playing. Green was also ejected on Jan. 4, 2020 (vs. the Pistons), Feb. 27, 2020 (vs. the Lakers), Feb. 20, 2021 (vs. the Hornets), March 20, 2022 (vs. the Spurs), and Jan. 4, 2023 (vs. the Pistons). If you count Green's ejection on Tuesday, seven of his last 11 ejections took place in games that Curry wasn't playing in.
I think this is just a coincidence.
The options I can see:
Coincidence
Draymond doesn't want to play without Steph
Steph in a jersey is the calming force that keeps Draymond's anger from reaching critical mass
Draymond is in love with Steph and gets ejected as part of an elaborate mating ritual
I'm leaning towards number 2 but I wouldn't take 4 off the table
