You're referring to 'In addition, sequence input may be in the form of 
either a Bio::Seq object or or an array of Bio::Seq objects'? I agree 
its not clear, but supplying a reference to an array is still supplying 
an array. Anyway, I'll clarify it.


In any case, the usage for the method is what you should pay attention to:

It should be exactly what it says. A reference to the array.

Returns : Reference to a Blast object or BPlite object
            containing the blast report.

That means, just one big object, not an array.
