From my view, at moment S0, the map matched point was '2' (second candidate point of S0 with thick circle) in the picture. At moment S1, the map matched point was '4'. At moment S2, the map matched point was '3'. The output sequence we recived would be 2 -4 -3. However, at moment S2, we get map matched point 3 by the most-likely sequence of 4-4-3. My question is, does this mean the already output map matched point at S0 and S1 is wrong? Or it is an acceptable result since we could only infer 2-4 at S0 and S1 with limited information, but we correct it at S2?
