Can someone explain why my teammates don’t spawn on me?

I know it’s hard to see, but I got the theater mode view such that I could confirm that there were no enemies behind the hard point.

I went all the way in the back behind the turret to block spawns and get my teammates to spawn on me for P3. But for the first time ever, my teammates, nonstop spawned in P1. Even at the moment where all three of my teammates are dead, they still did not spawn on me.

This is maybe the most illogical spawn I have ever come across. If anyone knows how to get the mini map view of my theater, please let me know.

Can someone explain why my teammates do not end up spawning on me?
