Is doco wrong on ifEnum.isEmpty() ?

I am confused about isEmpty() on enumerables. RTFM implies isEmpty() is the opposite of isNext():

“ifEnum” wrote:
…
IsNext() as Boolean
Returns true if there is a next element

IsEmpty() as Boolean
Returns true if there is not a next element
But the two do not stay in sync:

BrightScript Debugger> a = [1]
BrightScript Debugger> ? a.isEmpty(), a.isNext()
false         true
BrightScript Debugger> ? a.next()
 1
BrightScript Debugger> ? a.isEmpty(), a.isNext()
false  false

Seems that (and i am hoping that) the actual meaning is: isEmpty() returns whether the object has no elements (regardless of where next pointer currently is).

Is this correct? I am asking for realz, got a list - want to check if it is empty and o.isEmpty() sounds as a better/properer way than checking o.count() = 0.
