Another way of looking at it: MS has to work with institunional investors in the future, Musks wealth is coming from one company as is mostly paper value and not cash. Letting the deal fall through, if that is legally possible and doesn't expose MS to legal risks, might paint MS in a bad light. And that impression, that MS is willing to play legal shenenigans to favor one party over others at the expense of the spirit of the agreements, might something they want to avoid. Especially if they could get a chunk of Tesla or even SpaceX. In the end, we will only know if, or when, Twitter and Musk struck a deal or, ultimately, the courts issue a ruling whatever that will be.
