What is the difference between ArrayIsSeries() and ArrayGetAsSeries()?

 
What is the difference between ArrayIsSeries() and ArrayGetAsSeries()? When I checked an array, for example high[] array in the OnCalculate(), one of them is saying true and one of them is saying false ... and I can not figure out the difference between them from the documentation. Any help? Thanks a lot.

What can be the utility of the function ArrayIsSeries ?

I wonder why this function exist and how it can be used for an useful task ?

There is often confusion among programmers between this function and ArrayGetAsSeries, even in some good articles. Maybe there is historical reason or I miss something.
