That seems to work most of the time, however I tried it with my own button and Team clutches, using the new Polaris tool, the team was off .040". It's actually not a special tool, but rather the new recommended tool from Polaris SPX.---- I have since sold the team though.
What I like about the new tool is it fits on the face of the primary, self aligning on the face, doesn't hook behind the primary like the old tool, so it works on clutches with the starter ring gear, it also can be used on the button clutches to more accurately align them as it measures to the outboard sheave on the secondary, instead of behind the inboard sheave.

Thanks for the explanation Don. I have both types of tools.
However, it seems to me that you want to align to the backside of the inboard sheave of the secondary so that any belt wear adjustment is accommodated and you can check parallelism both front to rear and top to bottom.
I.E., as you adjust the deflection for belt wear, you are actually misaligning the belt, so the converter has to be moved in a little. BTW, this is one reason why I usually float a typical secondary towards the inside.
When I install a different engine into a particular chassis, (Such as an RX-1 engine into an F-7 Firecat) I use a level to get both the engine and the jackshaft parallel to each other first. Then use an offset alignment tool to recheck at top and bottom of both primary and secondary on their backsides.
All the while maintaining proper center to centers. The final procedure is belt deflection and the final offset adjustment. Always gives excellent belt life as long as engine movement under load is minimal.
