onParametersSetAsync is being called even though params has not been changed

I'm trying to figure out how Blazor behaves. I'm debugging something by temporarily removing commenting out other code so as not to be destructed and make sure with what I am observing. The code looks like this.

<OneComponent @ref="_oneComponent" param1="@varParam1" param2="@varParam2"></OneComponent>

@code {  private OneComponent _oneComponent;   private _objectOne varParam1;   // There are values here.  private _objectTwo varParam2;   // There are values here as well.  private async Task SaveClicked()  {    if (_oneComponent.OnSaveClicked())    {      // nothing here.    }  }}

When I run the program, I noticed OnParametersSetAsync() of <OneComponent/> is being re-run.My question is, why is OnParametersSetAsync() being re-run again even though I didn't change any of varParam1 or varParam2? Is that what it is? Should it re-run when the program now points to that component after the _oneComponent returns true or false?
