Report in 'Private Flying' indicated it landed on 23L, in which case it would need to 180 and backtrack (there being no taxiway from the south west end of 23L to the terminal) to get to the terminal which it obviously could not do.
I presume when using the 23 direction that 23L would normally be the departure runway with 23R for arrivals; on 05s then they would normally use 05R for arrivals and 05L for departures.
