Default Power pins interconnection of a STA516B

I was wondering if any one could tell me if it is normal that the power pins of my STA516B are interconnected with each other.
I have measured a STA505 and those power pins where not interconnected.
The problem with the interconnection is that i get noise when using it in 2 channel mode, or am I wrong?

Just to clarify, with interconnection I mean:
VCC1a and VCC1b are interconnected with VCC2a and VCC2b.
GND1a and GND1b are interconnected with GND2a and GND2b.

And of course I bench measured this bare chip without PCB.
Maybe I have a counterfeit part?
