Yes. Rules for Ini-INVITE and Re-INVITE is in different parts.
But I feel that there's no conflict.

I think timing of "PRACK transaction is completed" is better.
But it seams that there's no problem for UAS sending UPDATE just after receiving PRACK(with out SDP).
If PRACK has SDP, then UAS should not send the UPDATE by O/A rules.
