Why were you looking at him? Weren't you watching your area? If you had a whistle and did not hear his, what would make you stop providing a mechanic? (just kidding about the 2nd question)
Seriously, whistles/mechanics are about communication, nothing more. Whistles involve our sense of hearing while mechanics involve our sense of sight. What is purpose of doing both simultaneously? (blarges and other contradictory signals can't be avoided using either method)
