The upward facing piston monostable is both orientational and coordinate dependant > Huge inconsistency

The upward facing piston monostable is very inconsistent.
I will show 4 situations, each with 2 inputs, 2 pistons as outputs, and 2 pictures of what happens when I flick the first or second lever.
Each of this has the lever above and on the left, and the pistons on the right and on the bottom. I will change the direction the pistons are facing, and move the setup for each situation.

In situation 1 (Picture 1 and 2), we see that powering the lever on top powers only the piston on the right, and powering the other lever powers the other piston.

In situation 2 (Picture 3 and 4), we see that powering the lever on top powers none of the 2 pistons, and powering the other lever powers the piston on the right.

situation 3 (Picture 5 and 6) is identical to situation 2, the 2 pistons are just facing a different direction, and are in a different location.

situation 4 (Picture 7 and 8) is identical to situation 1, one of the pistons is just facing a different direction, and are in a different location.

The top of the pictures is always facing f:2(North)
Also: I know this is a duplicate, but I just wanted to make the bug more clear

I really hate this bug, and I think it should be fixed by pre-release.

UPDATE:
Powering the monostable with redstone or repeater actually makes a difference.

EDIT: Since 14w19a, this monostable works consistently in one orientation, in the other however it is still coordinate dependant.
