What led you to come up with this interpretation? [3].    

A target *reference* will *always* export and create a clickable link
irrespective how the target is *defined*.

I think there is an element of confusion about what invisible target is.
After some digging, I realize that they were originally called as
invisible anchors.  

The manual [1] has the following note:

,----
|    * Matt Lundin has proposed last-row references for table formulas
|      and named invisible anchors.
`----

The original post [2] from Matt says
,----
| # <<radiotarget>>
| 
| should become
| 
| <a name="radiotarget"></a>
`----

Now the question is what is invisible? The "description" in <a ...> </a>
becomes invisible.  

Why was the term invisible chosen in the first place.  For this one has
to look at the the "default" behaviour for targets which is to export
with *both* the anchor name and anchor description.  

So, I think a correction is in order.
