Both of them are used to declare local variables

No. local does not declare a variable, as you can easily try out: 

$ perl -Mstrict -e 'local $x'
Global symbol "$x" requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.

If local declared a variable you wouldn't get an error message here.
