Contract of Sale and Depreciation Special Condition

I am reading a contract of sale and it states:
The vendor and purchaser agree that the value of any depreciable improvements, plant, equipment, fixtures and fittings owner by the vendor and passing under this contract shall correspond with the individual values assigned to each item in the Depreciation Schedule of the last Income tax return of the Vendors, but if any item does not appear in the Schedule or has no value assigned to it, the value is agreed to be ONE DOLLAR ($1.00) each.

In English please?

Should I be asking for the depreciation schedule from the Vendor that he used on his last tax return?

If its a generic depreciation schedule and ie the split system air conditioner is not mentioned, is the value only $1.

I typically thought you obtain a new depreciation schedule every time you purchased a investment property.

Any thoughts would be appreciated.

Cheers
