Well, interpreting an 'experiment' that one has not conducted him/herself without knowing _all_ parameters of the setup is not something to encourage doing.. Did you use symmetric (XLR) connections? Are the sample-rate settings of both cards identical? what was the physical distance between the devices (cross-talk)? Was there any ground-lift equipment (built-in?) in place or maybe you simply forgot to switch off phantom-power? Anyway, good that you've labeled it 'quiz'; so here's my guess: You're encountering reflections (or even standing-waves) in the cable. (did you uncoil it? or was it a very short one?) Did you repeat the measurement? using different cables for example.
