Yes that is the way things are
suppose to work, but the scenario that
you just explained does not appear to be the
case.

As previously mention,
The Lender's side of BitFinex is beginning to Look
more and more attractive, 14% interest compounded Daily ?,
that would be 420% monthly, not a bad deal, especially if one
adds in the fact of the Platforms heavy hand in protecting lenders,
it's a "No-Brainer", or in the U.S.A. it's called "Predatory Lending".

Not sure if it's just me or not, but that "Swap Interest Rate"
appears to be moving faster than should be when in a Leverage Position,
almost like a "StopWatch", never seen interest accrue at such a fast rate in my life.
