How is Invoice close tolerance working ?

Summary:

Hi,

I created 2 POs where receipt close tolerance is 100% and match level is 2 way, invoice close tolerance is 0%. Both POs have single line.

Created Invoice for PO1 with amount greater than PO value. PO is closed ( Qty remained same but unit price increased)

Created Invoice for PO2 with amount less than PO value. PO is closed. ( Qty remained same but unit price is decreased)

In both the cases po line amount and invoice amount did not match . invoice close tolerance was 0%. How come the status moved to closed without matching amounts?

What am I missing here?
