There are basically two flavors of AD syncing you can choose with Office 365 - Same Sign-On and Single Sign-On.  Same Sign-On is what you would get with a Staged Migration and the AD Sync Tool since it only syncs a subset of attributes and password hashes one way, e.g. no two way sync (except possibly passwords if you purchase additional Azure licensing).  True Single Sign-On is a full two way sync and the result of a Hybrid configuration using AD FS.  Make sense?

so you mean if I go by staged migration , am I not syncing all AD attributes on premise to office 365

what I asked was will my AD be gone from on premise if I do staged migration

also is dirsync now azure AD ? can I change password on 365 for AD user it will reflect on premise?

I though passwords change was one way from onpremise to cloud?

1. so you mean if I go by staged migration , am I not syncing all AD attributes on premise to office 365
    - Yes really only email attributes

2. what I asked was will my AD be gone from on premise if I do staged migration
    - No you can maintain the sync for as long as you need or indefinitely

3. also is dirsync now azure AD ? can I change password on 365 for AD user it will reflect on premise?
    - DirSync is still DirSync.  You can change passwords in 365 if you have Hybrid or a premium Azure license and the AD Sync Tool

4. I though passwords change was one way from onpremise to cloud?
    - It is a one-way sync if you use the AD Sync Tool and a Staged Migration
