That seems to be the case.

But what if you only want the last element or the 5th? I guess selecting
the last element can be just as usefull as the furst.

It seemed a bit overdone and somewhat arbitrary (why not an option for
selecting the last element?). I think performance is a good argument why
it may not be overdone, but only providing a single selecting option for
the first element and not for the last one still seems arbitrary. I
don't think there's a performance argument behind that decision, but I
can very well be wrong.
Anyway, if there is going to be a method for selecting a single element
I'd rather like to see both (first and last):
These method names (the single selecting method names being variations
on that of the plural method instead of the other way around) would be
more clear as well in my opinion.
