Without knowing the exact date and time that the images were taken and with access to someone on shift at the time, it's impossible to give a definitive answer so here are some "myth plausibles".
Mapping images are stitched together from different frames from different satellite passes by software. The software will select two images based on contrast, clarity and other optical attributes or perhaps because of data corruption. Whilst this image is made up of at least two frames from different times, I can see no signs that the two aircraft are from different frames.
A controller made a mistake and cleared two aircraft onto the same taxiway at the same time. It's happened before, it will happen again. However, these are tail to tail and I cant think of anyway that this could have happened.
The only remaining explanation I can think of, and the evidence points to this being the case, is that the taxiway is being used for temporary parking. The ramp is pretty full and it is plausible that the two aircraft have been parked tail to tail so that either one can get out without having to move the other.
