Thanks for the added info.
I can see no problem at all with what you have now posted. The Company Ops Manual requirement for the FOs to
also be PF for Take Off and Landing in order to Log PICUS would be additional to, and does not contradict, the other requirements (and I can even see some merit in the practice).
It is the assumption that PF, on its own, automatically means PICUS that I do not like.
