Inconsistence between HTM and 3D-HEVC text in IvDC pruning

Description

In derivation process for luma motion vectors for merge mode, pruning of IvDC with A1 and B1 is incosistent between HTM and 3D-HEVC text.
In HTM, if A1 or B1 is identical with IVMC (or T), it is marked as unavailable and is not used for pruning with IvDC. However, in the 3D-HEVC text, even in this case, A1 or B1 is still used for purning with IvDC, which is not reasonable and should be aligned with HTM.

Is the fix still necessary? And does everybody agree that the spec needs alignment? In the suggested fix B1 can be added although availableFlagB1 is equal to 0. Is this intended behavior?
