True and false do nothing in commands. Example: /effect @p speed 33 3 false will still give the player particles.

Thank you for your report!
However, this issue has been closed as Working as Intended.
If you want to hide the particles, use the command /effect @p speed 33 3 true (This works correctly in 1.1.0.9)
