That does seem to be the
gist of it. It's a bit vague on when and how disqualification would/could be applied, but for now "whether Trump prevails in the primary process" is hypothetical, and hypothetical injuries are not a cause for controversy.
The timing of that disqualification is certainly a potential cause for disaster. In the lower court ruling [first whole paragraph on page 6] it notes that even if Trump were elected in the general election, Congress
could remove his ineligibility [as also allowed by the 14th Amendment (by a two-thirds vote)]. So when will we ever know if Trump is actually disqualified? Presumably sometime between the general election and the inauguration. It seems unlikely that Trump can get a two-thirds vote, so if he 'wins' but is ineligible, what do we do? Call a mulligan?
