Question about exposure:

Right now in the Beta we are seeing exposure at 1%.
1 VERI to 100 ETH.

In the future it was mentioned that it could be 5%.
1 VERI  to 20 ETH.

Assuming I plug-in 1 VERI and assume the 1 VERI/20 ETH exposure in the VeADIR platform:

Question: Can I buy 20 ETH worth of product for 1 VERI? Or not?

What's the point of the exposure? Are there any other benefits? Why not just 1:1 exposure?

Thanks for the help.
