For a binary mask EDT computes only distance for true pixels (with value of 1). Thus when calculating EDT only one time you get distance transform only for foreground mask (pixels with value of 0 stay as 0s). To calculate it for all pixels you need to invert the mask and run through EDT once more to obtain distance transform for background mask.
When you sum those two masks you create unsigned distance field and when subtract either one from the other you create signed distance field (one with negative and positive values). In paper authors describe that they used unsigned fields but I've run a couple tests and both unsigned and signed fields as well as one way transforms e.g. foreground and background, seem viable. This may depend on imbalance between the segmentation classes and segmentation shapes in particular problem.
