Reflection on the surface of polished metals occurs because of the collective movement of electrons at the surface, caused by the incoming photons. Light of most wavelengths, especially low-energetic infrared doesn't have enough energy to cause orbital transitions in most elements.

Looks at first sight like much of a bigger coincidence, but given that you probably both used a long shutter speed (yours seems to have been 6s) and selected the nicest of a number of shots, it's not like there are crazy chances against getting two almost identical shots like this.
