It is basically saying this. Current level is 95, if the EU influx hadn't happened then it would've been 100. Leaving the EU won't automatically mean it will head back all the way to 100. Other factors are in play, but it might end up at 97. One of which that the presence of those already here will limit its recovery. If we stayed in, the 95 would drop FURTHER to 94, 93, ... 90. We can't undo the effect of the previous EU influx, but we can stop it increasing yet further and having a greater detrimental effect. Whichever way you look at it, they are worse off because of the EU, and would be even more worse off if we stayed.
