We’re on the same page length

Describing a positive experience in a job interview, the speaker felt that he and the interviewer were “on the same page length”.  This is a nice congruent conflation of “on the same page” and “on the same wavelength”, both meaning to be in agreement or thinking similarly.  Both idioms have the words “on the same” and share similar sounding words – “wave” and “page”.  I can see where this would be a commonly used malaphor.  A shout out to Amy Silver Desmond for hearing this one and passing it on!
