Spindle direction signal when stopped

Still on the old flipflop, PathPilot V1 has no functioning halcompile, tried many ways but tripped up every time
What I have is (relevant part):
After starting PP what I expected to see was:
1) last-spindle-direction-latch.out (flipflop out) HI
2) spindle-dir-latched HI
3) hm2_5i25.0.gpio.005.out HI
but they are all LO, the flipflop is not set by the setp line
Once running it works as it should.
FWD RUN:
STOP after FWD RUN:
REV RUN:
The STOP after FWD RUN is what I was expecting initial state to be.
What am I missing?

loadrt flipflop names=last-spindle-direction-latch
addf last-spindle-direction-latch servo-thread
# spindle direction
# P3 pin 16 gpio 005
setp hm2_5i25.0.gpio.005.is_output 1
net spindle-cw motion.spindle-forward => last-spindle-direction-latch.set
net spindle-ccw motion.spindle-reverse => last-spindle-direction-latch.reset
# pre set flipflop out hi, forward
setp last-spindle-direction-latch.out 1
