passing along the backline even if you are 1 goal down has a tactical reason to it. It is meant to "open up play" like passing to flanks and changing sides, passing to the back and having the back line pass around "invites" opposition to come forward to attempt for possession creating space in the middle or even up front. if there is no space or things get to compact in midfield, sometimes passing to the back to "relieve pressure" in the midfield or use diff tactics like to suddenly launch the long ball by passing midfield when it is packed with ppl is another option. It is also useful for composure, imagine in epl the moment you get the ball in midfield in a split second the other players are at you. Those who play football would understand that the more touches you have and more time you have on the ball, the more assured and composed and more confident you are. hence the passing to each other at the back gives you time and space for the defenders to be composed and imposed themselves. This is important esp to the back four. Imagine getting the ball with you not touching the ball the whole match and suddenly u have it with ppl running at you. You will panick and prolly miscontrol the ball, make a blunder.

In the EPL, the team that imposes themselves and finds their composure first will have an advantage, thats why some lower teams adopt a "in your face" tactics very direct to prevent the top teams from establishing themselves or else once the top teams find their feet, they will definitely outclass them. I wouldn't say it is negative football. It's just like playing the ball to the corner for time wasting. If you're good enough, come get it. And some have captialized from the back passing intercepting it and scoring too. Those who take long to take a free kick / goal kick , however those are negative as they make no attempt to play the ball at all(and now rightfully refs are giving out cards for them) . In the end, each team will have to deal with each of the tactics they face (even including "parking the bus") or direct football, as long as it is legal (not crazy tackling, diving, time wasting taking free kicks etc) deemed by the ref, what ever "tactics" adopted by the team the other has to deal with it not sulk and say hey they are not playing football the way it should be played.
