It sounds like someone is doing something funny with the
coordinate system. Without an example document to look at I don't
know how much help I can give. In particular with just your example
matrix above (1 0 0 -1 tx ty) your text should come out upside down.
Assuming someone had a similar vertical flip matrix outside of
yours you would see that increasing y would move 'up' the page.
Normally Illustrator doesn't do this but it's possible that in some cases
(like symbols) it does add such a transform (Illustrator uses a
standard Cartesian coordinate system Y is up, SVG uses a 'computer
graphics' coordinate system Y is down).
