Some pistons don't update / redstone wire doesn't schedule an update upon turning off / piston updates before redstone wire

This is not a duplicate of MC-108, as nothing powers the piston from neiter two blocks above, nor diagonally.
When I flip the lever off, one piston stays extended and will retract only when updated. It may relate to MC-108 still, but only if the cause of the bug is that piston gets updated before another piece of wire to the left of it gets turned off.
