Please use SHOW CREATE TABLE instead of DESCRIBE.

Let's double check your observation doing the following two statements around each SELECT:

FLUSH STATUS; -- run this before the SELECT
SHOW STATUS LIKE 'handler_read%'; -- run this after the SELECT

If that show significantly bigger results for the first SELECT, then please submit it http://bugs.mysql.com/
