That's quite normal, it completely depends on how the network is laid out (different fibres going in different directions, etc.) We have 4 lines connected to the poles outside our property, 2 are fibre (Openreach and Airband) and 2 are copper (original copper line and replacement copper line for our property to fix an ongoing fault in the past). I think most people aren't too bothered about how it looks, especially if they could only receive a handful of Mb/s before. I have seen the likes of Google Fibre twist their fibre round other cables, but not in the UK.
