If the sign of the cell has already been set, we check if it matches the seed sign and then we skip the cell, otherwise we set the sign of the cell and we process its neighoburs. Once the sign of a cell is set, we can remove it form the seed list (there is no need to start again the porpagation from that cell, beause it will not reach any new portions of the domain).
In some cases, the level set may not be able to identify the sign of a point. However, even in these cases, it is possible to evaluate the unsigned distance.
