I interpreted this comment as saying that they should test whether the coefficients are equal to 0 before interpreting them. There’s evidence that they did this if you look at the “if you’re into algebra” sidebar on the right—they dropped the m3 variable because it had a large p-value.

Is that what you were getting at?
