Yes, you are right. I can see the same issue on many of my documents (I
wasn't able to find any which would have the base of coord system at top
left corner).
The attached patch fixes this but please note that this might be not
correct as the coord system depends also on rotation and other things. I
will post the patch to our devel mailing list. Let's see what other guys
say.
You can apply the patch in two ways. Either you apply it in the source
tree and then run make install or apply it directly to the installed
file (which is in $PREFIX/share/pdfedit/ directory - where PREFIX is
/usr/local/ by default).

gui: Edit page metrics coordinates fix
Roger Burrows has reported that "Edit page metrics" labels expect that the
coordinate system is based on the left top corner which doesn't seem to be
the case for his documents (as well as my randomly picked up ones) where
the base seems to be at left bottom corner. In this case we have to change
the labels
