If you look at the effective chainstay length, you'll see it's not actually a very short wheelbase.
By not having to fit the chainstays between the tyre and the chainring, however, it should be possible to make a very narrow Q-factor. It looks like the stays have been spread far enough that the cranks can be inside the 'chainstay' line. Potentialy, the BB shell width could be cut from the normal 68mm to about 30mm. O'Bree used a similar trick to get a very narrow stance on 'Old Faihful'
