There is a similar situation at St. Jame's in Toronto, Ontario, Canada. Although this cathedral is much smaller in scale than most UK cathedrals, it is no small building. But instead of having two organs, the majority of the organ is separated into two in the chancel (pulpit and lectern, speaking into the south choir and aisle and north choir and aisle respectively) and to support congregational singing and for special effects, there is an antiphonal division at the west end of the nave.
This division is very effective in playing duos or dialogues. For example, once when the JSB Passagalia was played, the organist alternated the repeated arppegios between the great and the swell with great effectiveness and interest. Similar effects can also be created with a front vs. back echo effect rather than a left vs. right response effect.
It's a mavelous instrument. Quoting the website, "ST. JAMES' CATHEDRAL ORGAN is a fine English Romantic / American Classic instrument in beautiful acoustics with a large, colourful antiphonal division on the rear wall of the Cathedral. The organ was built originally in 1888 by the Samuel R. Warren Company of Montréal, Québec, and then expanded and maintained through the first three quarters of the 20th century by Casavant Frères of St. Hyacinthe, Québec. The solid-state console was built by J.W. Walker of England in 1979. Since 1999 it has been maintained by Andrew Mead and Associates, Port Hope, Ontario."
Also, because the organ is so close to the nave, evident from the second and third photo, (because of the lack of a crossing and trancepts) the experience is even more "up close and personal".
