Conditional act differently to direction changes than non-conditional

Conditional commandblocks act differently to a change in direction than non-conditional. This is apparently caused by commandblocks checking the block BEHIND them. Chain continues again when a non-conditional commandblock has been placed.

Regular commandblocks however do continue functioning after a change in direction.

Has been submitted before a long time ago and been marked as works as intended. Thought I would submit it again since I am not the only one thinking this is a bug.
