SQL Server Management Studio highlights a word that does not appear to be a reserved word I don't like to name objects with reserved word (i.e. Set) for all the obvious reasons.

So when SSMS highlights a word in blue, I rethink my naming of the object.

Every once and a while I see a word highlighted that does not appear to be in the list of reserved words. In this case the word pool.

Does SSMS use a more strict convention for highlighting reserved words?
SSMS uses color syntax highlighting for keywords that are not necessarily reserved keywords, but are keywords in the context of certain statements.  For example POOL is a keyword as in CREATE RESOURCE POOL.  SSMS will show the word in a different color even when not in the context of a CREATE or ALTER resource pool.
