Insolvent doesn't mean that the company folds up shop immediately. As the person you're replying to points out, it is possible (if unethical) to lie about being insolvent.
And, as the other reply to my comment pointed out, there's a decent likelihood that Tether is actually already insolvent and is doing creative accounting to get the numbers to appear to come out to solvency. 100.2%--especially when a significant amount is in as volatile an asset as cryptocurrencies during an upswing--seems too precisely close to 100% to me to not involve some amount of shenanigans.
