Remove -> re-add technician effect on tech history?

Remove -> re-add technician effect on tech history?

If I remove a technician's account, then re-sync AD , then re-add the technician with the same credentials, will he still be attached to his long term history on requests and changes and custom views?

I have a tech who is getting weird behavior and I believe this is a solution.

Thanks
