Front wheel hub, quick query

[canuck]

Chaps,

I noticed a machined section at the inner casting on my front wheel hubs.  As one can se the lip that holds the oil seal is not particularly thick.  

Is this the norm? Does anyone know why? I suspect to clear the brake back plate & fasteners?

Thanks in advance
