There is nothing in the website you posted that prevents the convention from picking Joe Biden, and him subsequently becoming the party nominee. I don't think that will happen, but the fact is, it could be done if the DNC so desires.

There are State laws that set deadlines for when candidates/political parties must file.
Go look at the dates again.

Does the DNC trump State laws or are they subject to them?

Texas Deadline for Independent Presidential Candidates Passes May 9, 2016

Monday was the deadline for independent candidates for president to get on the ballot in Texas.
Nobody showed up.
The Texas Secretary of State’s office, which administers elections, closed its doors Monday afternoon with no applications. And they would have noticed, too: Independent candidates have to submit their names along with petitions from 79,939 registered voters who, like the candidates themselves, did not take part in either the Republican or Democratic primaries.
