The help for Call-Async-Activity method says "Use the Call-Async-Activity method to load data pages asynchronously (into background threads) to allow other processing to continue"

In my view data pages can be loaded asynchronously just by using Load-DataPage method. Why is this method required then in the context of data page loading asynchronously??

Can someone from product team clarify?

Using the Call-Async-Activity method

Use the Call-Async-Activity method to load data pages asynchronously (into background threads) to allow other processing to continue.

Note: To run an activity asynchronously, set Usage on the activity's Security tab to "Asynchronous".

Only the following step methods are available:

• Load-DataPage
• Connect-Wait
• Call-Async-Activity (step instruction to allow the user to load an asynchronous activity)
