The problem is the lexer you use. You took "Plexer.make ()" which
considers "abcba" as a token, therefore not matching the keywords
"a", "b" or "c".

To get the same result you should give the string "a b c b a" as
input...

... or use another lexer, not "Plexer.make ()", which would return
each input character as token. It should be easy. If you need help
to write it, ask me.
