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.
