Automatic Transactions

[gnucash at ew.ewheeler.org]

The automatic transaction editor's heading changes from
   Tot Funds In / Tot Funds Out
to
   Debit Formula / Credit Formula
after clicking on a line item to edit.

This has always confused me.  I learned that the 'Tot Funds In/Out' 
headings are acurate in the way that I understand the meaning.  To me, 
"Tot Funds In"=="Credit Formula", however this is now how it is written. 
Several times I have had the columns backwards and transactions debiting 
where they should credit.

Is this (percieved) backwardness intended?  If so, can someone offer an 
explanation of why the meaning changes when viewing vs. editing?
