In 15w34b, Mojang introduced a new "Conditional" toggleable feature for Command Blocks. Similar to a comparator, this feature allows clock strips to only execute commands based on the prior command's success count.


Condition Clarification (Thanks to Skylinerw)
--------------------------------------------------------
An important distinction to make is that it's not necessarily the command block "BEFORE" the conditional block that's being checked, but the block touching the SQUARE SIDE or "BEHIND" it.

#4 is set to conditional and REQUIRES #1 to be successful in output, not #3. It needs #3 in order to connect to the chain of commands.
So instead of checking the command block passing a chained signal, it checks the opposite direction that it's "facing".
