How can gdebugger support GPU debugging even with single GPU?

If HW doens't support debugging..

Seeing graphics Core next seems AMD addes GPU HW debugging support similar to CPUs and GPUs from Nvidia.. but how can it be that gdebugger supports even with current cards from AMD: see "gDEBugger‘s single-GPU debug capability impresses at SIGGRAPH"

even single GPU doesn't make sense as when a breakpoint is achieved GPU would lockup as Nvidia says is reason for needing two GPUs in Nsight..

can AMD engineers shed light on this.. or what will then be core next debugging support add?
