The other Easy was probably holding at G1 ready to enter 09 once your aircraft had landed and stopped/exited the runway. Because of this, a quick backtrack to Taxiway F was required.
As you probably know, the runway in use is usually determined by the direction of the wind. If there is very little or no wind pilots can (IIRC) request either runway. It was probably quicker to land on 27 than to join the approach for 09, where as the other Easy would have shaved a few minutes off his flight by using 09 for departure. It’s not uncommon at smaller airports.
