Note how it says: "match the performance of the LuaJIT interpreter" (emphasis mine). LuaJIT basically has two parts: an interpreter in handcrafted assembly which is quite a bit faster than the standard Lua VM, and the actual JIT, which is even faster. IIRC on iOS the JIT is not allowed but the interpreter is still there.
