We are very sorry for the late reply but:

Composition option in TexBlend - is used to composite Texture B over the Texture A - using Alpha channel of Texture B.
For example if your Texture A is white color (255,255,255) and Texture B is black (0,0,0) if Composite is off you will get a 50/50 mix of both texture - so your result will be one color texture (128,128,12,
But if your Texture B has alpha channel with black dot on a white background for example and Composite is ON - Vray will mix both texture depending on the values of the alpha channel >
When alpha channel is black only the Texture A will be shown - and where the alpha is white only the Texture B will be displayed (if Blend Amount =1)

It seams similar to 2 sided material

Two Sided Mtl and Blend Texture are two different concepts - although both of them blend textures they are used in different situations.
