As I understand it Totem did in the beginning of shooting for VGHD ask the girls to not be to explicit. This seams to be changing now but when these girls had their photo shoot the aim was to make the new version softer and more teasing erotica.
Starting with "Silver Take 2" the material in VG2/SS2 and VGHD are the same. This is why the content of VG2/SS2 did become more soft in the last year.
Personally I hope they bring them both back and give them the freedom to go wild and crazy on stage ;)
