Shao and Ange1

Does anyone know why shao and ange1 switch their roles like frequently and every some time?
Sometimes i see ange1 playing smokes, and know he's playing initiator. Then it goes the same with shao.

"0-2 against KOI
0-4 this split
0-8 by maps
Have no words tbh. It feels like something got broken in our team after 2nd Heretics lose in playoffs. I want you to know, most of us would bench themself if they could. Dont even know about our chances to go playoff. Sorry." -Ange1

I think Shao said back in Split 1 that this year he told ANGE1 he'd switch to smokes because ANGE1 is a lot more comfortable playing initiator and Shao enjoys playing smokes so ig that's why
