Seeing double

While people were getting off the train at L’Enfant Plaza this evening, I caught a glimpse of a guy about my size and my build. There were two specific things I noticed about him. (1) He was wearing a Yankees jacket, just like the one I was wearing; and (2) he was carrying in his hand, the same book that I am currently reading, Rob Sawyer’s Hybrids. That was all I could make out and then he was lost in the crowd, the doors closed, and the train continued on.

There are two possible explanations: either it is a complete coincidence; or at some point in the future, I will be sent back in time and end up being seen by my past self while trying to make a quick getaway.
