Mismatch between SW and spec on parallel merge estimation region

Description

In VVC spec text D8, position offsets are used to determine the availability of neighboring CUs, for example, (0, -1) for top CU, (cuWidth+1, -1) for top-right CU.
In VTM8.0, function PU:isDiffMER(pu1, pu2) is used to determine the availability of neighboring CUs. But it’s using the neighboring CU’s top-left position relative to current CU.

It appears a mismatch between the text and SW. Suggest to align SW with the text.
