Direction in conditions doesn't seem to work

I am using the following script:

st=>start: Start
e=>end: End
opy=>operation: statements
opn=>operation: statements
cond(align-next=no)=>condition: Condition

st->cond
cond(yes,left)->opy->e
cond(no,right)->opn->e

The yes and no paths are always bottom, right respectively, ignoring the directions I've set.

Is there anything wrong with my script?

left does not work on conditions
