Greater Possession and continous use magic items

[ShiroK]

If someone casts greater possession (new from Occult Adventures) does it suppress their continuous use items? (It's specifically NOT a poly-morph effect) Specifically would say would a headband of Int be suppressed or continue to function?

For that matter does suppressing an item reset items that require attuning before use?

I'd say no. Think of the only difference between Possession and Greater Possession as the latter sticks your body into some equivalent of an extraplanar pocket while you're remotely controlling your target. Your body still exists, it's just not physically accessible while you're possessing.
