Speaking of old BASIC interpreters, does anyone know out why DECSYSTEM 20’s BASIC had a “LISTREVERSE” command? 

Yes, it actually did exactly what it sounds like!

DECSYSTEM 20 BASIC User's Guide: LISTREVERSE command

LISTREVERSE
LISTNHREVERSE

LISTREVERSE and LISTNHREVERSE print the contents of the user's memory area in order of descending line numbers. LISTREVERSE precedes the output with a heading, LISTNHREVERSE eliminates the heading.
