Can a VT technician also work on snubbers?

At ANO Mechanical Maintenance contracts out the snubber work to one company.

The contractor provides the testing, building, removal, installation and the VT Technicians.

The question was raised to me if a VT technician can be involved in the removal and installation of a snubber that they will also perform the VT on.

My opinion is: A VT can remove a snubber after performing the AFVT, but do not allow the VT to be involved in the install, IF they will be performing the ALVT. This being said the VT tech also has the remove and install qualifications. 

What do ya’ll do? What do you think of my opinion? We cannot find anything written that discusses this at all.
