doesn't help that the second para doesn't make sense anyway
If you are at the back when do you try to recover back to the centre line and when do recover straight away ready for the split step?
You always recover straight away - what is the point in waiting?
To try and answer the question I think you're trying to ask... If you are under a bit of pressure and have high lateral velocity (away from court centre) and/or when taking the shuttle in a deep corner, your partner should be more aware and more biased to covering x-c replies since he is the only one that can return them. In this case you would not necessarily try to recover to centre line since you would have to cover more straight/block returns than normal
