Strange result after an information_schema query

Doing some work on a MySQL DB I found that a simple query like the following:

select
	table_name
from
	information_schema.KEY_COLUMN_USAGE
where
	table_schema = 'db-name'
	and referenced_table_name = 'table';

Select allOpen in new window

was showing a list like the following:

 table_name 	
sql.php?table=table-one&token=3d38d6f1a9fc11efb91793b8d6745f04
sql.php?table=table-two&token=3d38d6f1a9fc11efb91793b8d6745f04
sql.php?table=table-three&token=3d38d6f1a9fc11efb91793b8d6745f04

Select allOpen in new window

instead of a simple list of the tables referenced by the table "table" like this:

 table_name 	
table-one
table-two
table-three

Select allOpen in new window

Is there any acceptable explanation for this?
