What is the difference between the rear derailleur with the two
sprockets on a short arm vs. the one on a long arm. Where the sprockets
are either close together or further apart. Is the longer arm for a
triple crankset to take up the extra chain?

Long arm rear derailleurs are also used with single or double chain
rings when you have a wide range cassette or freewheel on the rear.
Yes, it's to take up the extra chain and give to you room for the
large sprockets
