WPF binding paths normalized under the hood?

Question

I'm just curious, it doesn't matter if I repeat a subpath to some property in each binding or bind a DataContext and specify only relative paths in the bindings.

Examples:

Absolute paths:

<UserControl x:Name="uc"/>
  <StackPanel>
    <TextBox Text="{Binding ViewModel.Prop1, ElementName=uc}" />
    <TextBox Text="{Binding ViewModel.Prop2, ElementName=uc}" />
  </StackPanel>
</UserControl/>

Relative paths:

<UserControl x:Name="uc"/>
  <StackPanel DataContext="{Binding ViewModel, ElementName=uc}">
    <TextBox Text="{Binding Prop1}" />
    <TextBox Text="{Binding Prop2}" />
  </StackPanel>
</UserControl/>

I know that both bind the same properties, but I'm interested in what really happens behind the scenes, because maybe this can affect performance in situations where there are more than 2 bindings. Will the absolute path option have more “event traffic” because each of the text bindings observes the ViewModel property and its specific property? Or will it be exactly the same? I could imagine that the BindingManager resolves all binding paths, c. both options end in exactly the same IL.
