Just to confuse you more, balun is word constituted out of BALanced to
UNbalanced transformer. Assuming what you want to do is feed a long wire
with coax and do a "impedance match" to your long wire. What is needed is
an UNUN or UNbalanced to UNbalanced transformer as a long wire is feed
against ground and is an unbalanced load. The terms current or voltage do
not apply to UNUN's.

The author says they can be used for longwire.

So you say, but there is no such claim at the referenced Web site or
in the Construction Manual. Also, does it make any sense to refer to
it as a balun if it does not have a balanced circuit on the balanced
side?

You are correct. I mixed up something I read about my LDG 4:1 voltage
balun:

Is LDG correct? If so, then for a voltage balun and longwire, I
should use an RF ground on the second terminal. What if I don't have
one? Should I short it to the coax sheath? Or would a counterpoise be
better?

If I have a tuned counterpoise, should I use the current balun, or the
voltage balun?

If the voltage balun helps with a longwire, Can you suggest how to
change the wiring on the W1CG balun so that it is a voltage balun?

Also lost in the sands of time is the advice that a longwire needs a
9:1 or 10:1 balun. Is that true? If so, is that a current or voltage
balun?
