Yes, being an academic, I have read this (and many, many other) related documents.
No deal means no deal. It means (by its very definition) that there is a huge amount of uncertainty in what will actually happen. Take this quote from the document, for example:
"If there’s no deal, UK nationals will not need a visa for short trips, according to European Commission proposals. You could stay for up to 90 days in any 180-day period. You may need a visa or permit to stay for longer, or to work or study."
The first sentence is propaganda & potentially inaccurate, as the EC will not commit to anything until a deal is struck. If the UK imposes visas for short trips, then the EU will follow suit. The following sentences admit that students may need a visa to work or study.
Universities are of course trying to proceed as usual, and hoping that sanity prevails. But it's pie in the sky to think that we have made "contingency plans" for everything, when like everyone else we don't have a clue what it is going to happen next.
