Question:is this behavior valid by Maple using series command?

This is Maple 2021.1 on windows.

===================
restart;
expr:=x^(6+1/3);
res:=series(expr,x=0,6);
==============

gives
        O(x^(19/3))

But type of the above is not series:

===========
type(res,'series');
        false
===========

Yet convert(res,polynom) works

================
convert(res,polynom)
          0
================

Which is correct conversion. But help says that

"convert/polynom
convert a series to polynomial form"

Notice, it says "series" there.

So the input must be type series. But Maple says
O(x^(19/3)) is not type series. I think this is wrong. The
type returned should be series. Now the type returned is 'function'
from the series command.

What Am I overlooking here?
