Haven't read that link specifically, but this is specified (the difference between D120 and D124). You have e.g. a minimum cell endurance of 100k for each cell (D120), but you should refresh the whole EEPROM after e.g. 1M writes (D124) to /any/ of the cells (that is, counting all writes to all cells).
