In other words, EMC is sensing the home switch as being normally "tripped" and it then senses it as UN-tripped when the machine hits the switch. I only have home switches on my machine, and depend on the soft limits otherwise. I wonder if you have a HAL pin assigned for the home switch, and it is being sensed as true all the time. (I am guessing you are using your limit switch for home, but motion still has a HAL pin defined for a home switch.)
I was also quite confused when I first saw this backwards behavior, as it appeared to be homing to the index pulse, just not moving the way I expected from the documentation.
