Correct Jim!
This is an old trick for those that have zero room for a 160 meter
antenna. We often did this and loaded the whole shebang to be able to
get on 160.

Is this true, and if so, why?
No. With the shield disconnected, the antenna is different -- if
there's an effective choke at the top, it's now a long wire ending at
the choke, because the shield and the center are capacity-coupled
together. And if there's no choke at the top, it's a top-loaded long
wire.
