When using 'replace move' with /clone the command block executing the command won't set "triggered:" to false if none of the blocks of the destination region is adjacent to the command block. This only occurs when the power source powering the command block gets moved aswell.

Example 1:
1: /give @p command_block
2: place command block and insert: "clone ~ ~1 ~ ~ ~1 ~ ~1 ~1 ~ replace move"
3: place redstone block above the command block -> block gets moved
4: place another redstone block -> nothing will happen
5: destroy redstone block above command block and replace another one -> will work like step 3. Step 4 + 5 will repeat infinitly.

Example 2:
1: /give @p command_block
2: place command block and insert: "clone ~-1 ~1 ~ ~ ~1 ~ ~ ~1 ~ replace move"
3: place redstone block above the command block -> block gets moved.
4: place another redstone block and it still works properly. That is because an air block (or whatever is ~-1 ~1 ~ to the command block) is moved on top of the command block which updates it.
