I don't know why Wikipedia groups them, but it at least doesn't say that 
a center turn lane is a reversible lane.

"Two-Way Left Turn Only (R3-9a or R3-9b) signs (see Figure 2B-6) should 
be used in conjunction with the required pavement markings where a 
*non-reversible* lane is reserved for the exclusive use of left-turning 
vehicles in either direction and is not used for passing, overtaking, or 
through travel." (emphasis added)
