This ^^^^^^^.
There is nothing in the operational rules about who plays when in the play-offs.
While "traditionally" the higher placed team might well have played first, that was when Sky had both semi finals, now there's two broadcasters with Sky first pick.
Add in the fact that over the last ten years there's no advantage to playing in the first semi-final, in fact, the complete opposite.
=> A huge nothing burger as the Americans would say.
