YES it does, it must be unique.

A specific id is only allowed one per page.

Some browsers may be so forgiving when you breach this rule, that only the 
first instance of the erroneous multiple is taken as a reference.

That does not mean it is allowed or good programming behavour!

I heve never seen that getElementById() references multiple html-elements.
Then it should suddenly act like a collection?
You don't believe that yourself, methinks.

Methinks you are confused with the action of getElementsByName()
[ that has ...Elements... with a final s ]
