image Whether there is a problem with such path connections, randomly generated vehicles seem to prefer to walk on both sides of the road

However, in the third picture, the second source lane on the left conflict with the right lane. Why is that? and is there a problem if I force them to connect?

Generally, you should avoid have two lanes of the same incoming edge target the same lane on the outgoing edge. This creates traffic flow conflict which rarely occur on a "real" intersections. It will also impede traffic flow in the simulation just as it would in the real world. It gets even worse if you have two connections with the same source and target edge cross each other.
