I have read this thread throughout and learned a lot. I had not intended contributing until I read the above. I have to say this post makes me wonder if some people do actually know what they are doing. Ferris points two aircraft at each other when one is climbing and the other, I quote "The 737 had been 'manouvering vigorously', and was in a high rate of descent"
Of course the respective TCAS got worried and started shouting, what would you expect in these circumstances? Ferris please tell us why you allowed these two aircraft to point at each other especially when one was still apparently involved in a test profile. Incidentally I would imagine the RA to which you refer must have been of a very short duration and ceased before either aircraft had time to manoeuvre. Nothing at all to do with the "plan" just the fact that the aircraft did level off at their assigned levels.
