Vanguard EDV Return Discrepancy

[Technician]

Dear sirs, I have a question regarding the hypothetical growth of Vanguard's EDV Fund:

https://personal.vanguard.com/us/funds/snapshot?FundId=0930&FundIntExt=INT

Please see the hypothetical growth graph shows new highs in the past year.

But looking at stock chart http://www.google.com/finance?q=edv, the late 2008 highs were never neared.

What is the reason for this?
