The crankshaft turns two times while the cam shafts rotate once.
The 2T mark only indicates that cylinder 2 is at top dead center.
There is a rotational position of the crankshaft (within 720 degrees of rotation) for which none of the cam lobes force the valves open by pressing on the valve.
If both spark plugs have been removed, there is no resistance from compression to easily find that spot.
I see no reason to have the cam tensioner removed during this operation, except for previously cleaning and lubricating the tensioner's mechanism, but I may be wrong.
