Another interesting note about this:

At the point that I create the new rule and then edit it to set the
StopIfTrue value, that edit is applied to the correct rule. The very
next step, setting the font color, is applied to a different rule.
This is the section I'm talking about:

..FormatConditions(i).StopIfTrue = False 'Gets applied to the correct
rule
..FormatConditions(i).Font.ColorIndex = 3 'Gets applied to a different
rule
