Hi user_5359,
The `to` way of the relation (https://www.openstreetmap.org/way/1192245855) has 3 lanes in the turn direction (that is, going south). The Bing imagery shows that the left lane (#1) starts at this intersection and has a solid white line on the right, which is a typical thing for lanes that accept turning traffic; the other two lanes continue from the north. However the white line doesn't continue north (because it's possible to go forward (to the west) from https://www.openstreetmap.org/way/1192245857). That's why `connectivity=1:1` — you are supposed to turn left from the single lane to the leftmost lane. But there is no explicit sign/road marking to show that, so `implicit=yes`.
To compare, https://www.openstreetmap.org/relation/16118055 is also `connectivity=1:1`, but not `implicit` because that's a T-shaped intersection and there is a solid white line from north (https://www.openstreetmap.org/way/773851523) to south (https://www.openstreetmap.org/way/773851521), which you shouldn't cross when turning left.
