Now if you say, run the 1/0 into the building from the service head and than in the service enclosure, where bonded cgange to 6awg, that contradicts 250.64(C) where it states grounding electrode should be continuous without splice unlesss compression type connectors are used.
No it does not contradict itself.
The conductor from the service head to the panel is a 'Service Conductor' it is not the 'Grounding Electrode Conductor'
The Grounding electrode conductor starts at the bonding point in the service disconnect enclosure and ends at the grounding electrode.
If you chose to daisy chain more than one electrode together the GEC is the conductor from the bonding point to the first electrode. The conductor between electrodes is a bonding jumper forming the grounding electrode system it can have splices.
