Reuters Didn't Mislabel Spitzer -- He Was Just Standing "on the Right"

There was recently a brief flurry of a few incorrect labels of [former] NY Governor Eliot Spitzer -- noting him as a Republican. Perhaps the most inventive excuse for that mistake comes from Reuters via Newsbusters reader Doug M. Doug had sent an e-mail inquiring as to why Spitzer was mislabeled in this story. Here's the response from Reuters' Vincent Baldino:

Sorry for the delay in getting back to you but I wanted to look into
this. Our online photo editor just got back to me and confirmed that the (R) means that he is the person on the right side of the photo. It has nothing to do with democrat or republican.

Take a look at the picture and corresponding caption again. Being that only Spitzer and his wife are in the photo, why is it even necessary to indicate that the former governor is "on the right"? Doesn't "wife" denote "female?" Where else could Eliot Spitzer possibly be but on the right? In addition, wouldn't "(at right)" be the common method of indicating direction in a photograph?

You be the judge on whether Reuters' excuse holds any water.
