Good question... I'm thinking it's the same reason that with strict compilation enabled a variable in a repeat loop does not have to be declared as a script local. If it is declared as a script local no shadow error occurs. A handler parameter in a way is the same as it doesn't need parameters to be declared.
What is the scope of the variable vs. the handler parameter when the handler is running? That's bigger question.

It depends! Strict > compilation mode doesn’t care about variable shadowing. Never mind strict compilation mode, I think this should be a "compile" error anyway. With or without strict-compilation : variable shadowing with a script-local and a handler-local is an error. variable shadowing with a parameter and a handler-local is an error. why on earth is variable shadowing between a script-local and a parameter not also an error.
