Your company Operations Manual should state clearly at what point the Captain takes control during the landing roll, and indeed what positions the thrust reversers are left in. The Captain may deem a deviation from SOP as necessary depending on the runway surface conditions / weather / First Officer ability. It is however only polite and in the spirit of good CRM to discuss this prior to the approach. Random practice in assuming control at the whim of the Captain is demoralising for the FO and does not promote discipline nor skill-building.
I agree with Cpt Drag. Any doubt over what point the Captain takes control can be discussed during your interactive approach and landing brief which may make him think twice before wading in and creating an unhappy atmosphere.
"If the FO has tiller steering, why would the captain need to take control at all during the landing roll? Otherwise play it by ear, assume nothing and if you hear nothing continue flying the plane. If and when you can't make a turn, then ask if the skipper would like control"
......This may or may not be your company's SOP if you have dual tillers but for heaven's sake check your manual for conflict before you go applying your own initiative-based procedures.
