When I put a trigger to clip0 and then make clip1 it's allowing me to put a trigger in clip1 where I already have a trigger in clip0. This is a bug and I shouldn't be able to place a trigger where there is already one in another clip.
I ran tests and only one trigger is triggered. If you was to do this by mistake you would spend ages working out why your trigger wasnt triggering until you go through all your clips to find you've got two triggers in the same place.
I'm sure MP tells you a trigger can't be placed because one is already there.
P.S. Please bring back clip conditions
