[Mp4-tech] Deblocking filter Neighbouring Blocks

[Srikar Dasari]

Hi,
I am going through the ITU-T Rec. H.264 (03/2005) document for Deblocking Filter in section 8.7. 
In the begining of the section there is a note1about the availability of mbAddrA and mbAddrB. This is my understanding if disable_deblocking_filter_idc is not equal to 2, then even if mbAddrA and mbAddrB are available (like mbAddrA % PicWidthInMbs != 0; mbAbbrB > 0) and they belong to other slice, they will be considered as available. In the same section in step 1. derivation process of neighbouring blocks they are invoked with section 6.4.8.1 and in that availability was taken as not available, if they belong to other slice. 
My question is
Since the availability is not mentioned in step 1. Do I have to go with the availability as in note 1. or with step 1, as in section 6.4.8.1.
Please let me know, if I am not clear in any section or correct me if I misunderstood anything mentioned.
Thanks,
Srikar
