I think the (correct) presumption would be that Bernie lose. If that's the case then some people in swingy districts could vote Democrat to put a check on Trump.
Biden was presumed to defeat Trump so people in swing districts could split their ticket the opposite way.
A lot of house races were decided by tiny margins.
Polls showed that people were divided on whether they believed Trump or Biden would win. Since polls undersampled Trump voters and those voters overwhelmingly thought Trump would win, the electorate that voted likely believed Trump would win the election.
