Extract from messages on the dev-mailinglist:
[ erack:
Something is hidden in the help for "Array Functions":

| Using Array Formulas in LibreOfficeDev Calc You can also create a 
| "normal" formula in which the reference range, such as parameters, 
| indicate an array formula. The result is obtained from the 
| intersection of the reference range and the rows or columns in which 
| the formula is found. If there is no intersection or if the range at 
| the intersection covers several rows or columns, a #VALUE! error 
| message appears. The following example illustrates this concept:

And then follows a description of how to create array formulas, which is
exactly _not_ about intersections..

While the hint about the non-array "normal" formula mode is helpful there to
outline the difference, the actual "what happens in an intersection and when
and why ..." should (also?) be covered at a more prominent place

FYI, this is also known as "implicit intersection" in Excel terminology.
If you google the phrase "excel implicit intersection" you'll get quite a few
hits along with some interesting narratives.
