James;
I think you may be right.   I remember a couple of instances as examples.   One
guy I know (this is true) wrote his programs with named variables instead of
indicators BUT he named all his variables and routine names and everything else
as PARTS of SHIPS.   Routine & variable  names like Starboard, Port,  Mast,
Bulkhead, Porthole, etc.   DID NOT mean better readability.  
I worked with another guy once that named all his routine names, etc.  as
Russian General names (true story) Imagine trying to figure that code out!
But he was a C programmer so we thought it was normal.

On the other hand I have worked on RPGII code which used EVERY indicator (and I
mean Every) even U1-U8 and H1-Hx  It even moved banks of indicators (80-89) to a
save field, did a subroutine and then restored them.   WHAT A MESS!

Remember Named does not necessarly mean Understandable( to whom?)
