Good point. Mine really got stinky when it failed.
The problem is that when tested inverted, if the plug bodies are not grounded, the voltate generated by the coils will not be limited by the breakdown voltage of the plug gaps. So the voltage can get high enough to cause internal failures.
So if the DI is inverted, and the plugs inserted and each plug is grounded properly there should be no problems at all in testing to check for a spark at each plug. So the tricky part is the grounding of the 4 plugs.
Now any danger from air/fuel mixtures from the cylinders blowing upwards and getting ignited? I will not say no. So test with different plugs and leave plugs in the cylinders for safety.
