He's correct about "inconclusive".
But, that test is the starting point. The problem is either low compression in those cylinders or very low or non-existent fuel to the cylinders.
I'm far more inclined to believe the former, as the IP's rarely give the trouble that you've described. Additionally, I'd make a wager that the blue/white smoke is fuel smoke (you can smell it). This would confirm that you've got the fuel, but do not have proper combustion in the cylinder(s).
At that point, it is definitely time for a compression check.
