Yes, "if".  Aside from whether Pankaj should have
seen that:

People don't necessarily (or even often) read manuals
"in order".

Even when they do, it can help to put important terms
in a glossary, and add links from the glossary to
topics that also define, or otherwise expand on the
terms.

The Emacs manual has a glossary (`g glossary'), but
the Elisp manual doesn't.  It could have one too.

Links from occurrences to glossary entries (or if
no glossary, to a defining topic) can help.  E.g.,
put a glossary link on the first occurrence of a
term in a given topic, especially if understanding
the term is important to understanding that topic.
