As SOG says, when the oppo are pressing right up it's ridiculous to keep doing it. In that situation the benefit of it is that as those players are now so high, there is more space in midfield. The Arsenal goal as an example drove me nuts, as if Xhaka had moved forward he would have been in acres of space and Leno could have just clipped it over the top of the pressing attackers to him from the goalkick, allowing him to turn and push forward already behind the strikers and midfielders.
