Secondary Lien Same date same lender foreclosure auction Title Q

[John Rovin]

Hi I am checking the documents of a property which is in foreclosure.

It has below deed of trusts:

1. ABC Bank (FirstLien Deed Of Trust) $100,000 Date: 1/1/2000

2. ABC Bank (Purchase Money\Second Lien Deed Of Trust) $30,000 Date: 1/1/2000

If bank is foreclosing First Lien then, is the buyer at foreclosure auction responsible for "Purchase money/second deed of trust" which is of same date and same lender?
