* here converts an array to a list of arguments.

so,

in:

args_ary = [1,2]
hash = Hash[*args_ary]

it's the same as

hash = Hash[1,2]

where as 
args_ary = [1,2]
hash = Hash[args_ary]

is the same as

hash=Hash[[1,2]]

... which will give you a bunch of warnings and just set hash to an empty Hash.
