Not really.
The first point was known since he got fired (that he tried to "trigger" the special investigation), he said that in an interview months ago.
As for the second tweet, he may believe that Trump won legitimately, but also believe that Trump obstructed justice by firing him, and wants that investigated, and also may want to see the Russia investigation to its end.
Edit: not sure what's going on with the third tweet, I am missing context.
