The double VANOS technology itself appeared in 1996 (single vanos in 1992), but we are talking E53 here...

Umm, where did you get that info?
IIRC from all my years of owning BMWs, the 4.4 M62TU is a double vanos motor. Its in my 01 740i.
The N62 motors are Valvetronic, hence the N nomenclature.
S series motors are in the ///M cars and utilize the double vanos system also.
