Bob,
I get
{True,False,True}
Or@@%
Sequence@@%
Or[%]
{True,False,True}
True
True
True
The second output is from Or@@<first output> = Or@@{{True,False,True} ->
Or[True,False,True] --> True
The third output is from Sequence@@<second output> = Sequence@@True --> True
(Apply acts on FullForms, compare f@@a)
The forth output is from Or[<third output>] = Or[True] --> True
