In both cases your box would show 2 casts remaining, however they wouldn't know if they were at 20 or 25, meaning the latter would be ok to use Starsurge now if it's up whereas the former would not be ok and cost you dps.
What you could do is have a separate box color for when Starsurge is ok to cast in Solar (100,85,70,55,40,25,10,5) and then I different color if you only want to cast Wrath, thus saving your next SS for when the box changes color. The amount of casts remaining would always be accurate as long you followed the colors in the box.
