What...

 

Here is Gemini's explanation on the second Y and Z equations:

The standard definition of Pauli Gates.

On IBM composer:

                                                                               

In both cases, the Pauli gates are reversible ie two X gates in a row takes on back to the

initial position.

But the implementation seems a bit different on the X,Y sequence. Might have to do with

how the conputers work...
