Does "the cause of X and Y" mean "the cause of confounding X and Y to be associated"?

Thanks in advance
**********************
Illustration of a simple confounding case: in this graphical model, given Z, there is no association between X and Y. However, not observing Z will create spurious association between X and Y. In the latter case, Z is called a confounding factor. In other words Z is the cause of X and Y.

    Well now I rephrase my question:

    Does "Z is the cause of X and Y" mean "Z is the cause of the spurious association between X and Y"?

    Thank you. :)

    The English expression "Z is the cause of X and Y" itself appears to be a confound in the writing. I wonder how many native speakers would immediately get that "Z is the cause of X and Y = Z is the cause of the spurious association between X and Y."

    The expression is indeed very peculiar to me.
