The ejector spring/button serves only to "tip" the case toward the mouth of the open receiver cutout. The case then is moving at bolt speed, and at a significant angle to the bolt face when everything comes to an abrupt halt.

Sorta like a body falling flat, but then it's legs hitting one of Titanic's propeller blades after building up velocity from falling 100 ft. Things get nasty after that.

Watch the first five seconds of this SloMo video.

You will see that the case is moving backwards from bolt speed until the bolt stops; then it starts to spin from being at an angle to that bolt face (still moving backwards toward the shooter); then it's finally deflected to the side by the deflector "bump" on the receiver.
