So, an ATC Sqn commander is likely to be A/Flt Lt/Pd; VGS commander would be Sqn Ldr, etc. Probably what you encountered was the current boss and his predecessor; but the second Sqn Ldr could also be holding a post elsewhere (wing staff or CCF contingent commander).
The guy who replaced me as WGLO at 613 was a Sqdn Ldr WSO, so maybe it was him and the OC 613.
By the way, the highest acting VR(T) is normally Wg Cdr; Vorderman and Foy were given 'honorary' commisions as Gp Capts but I don't know how that fits in
