All of this is described pretty clearly in the spec. The entire description is a single short paragraph.

which I'll include here

Along with each ‘’, the author may specify a

directionality, similar to adding a dir attribute to an element in

HTML. The ‘image()’ function takes on the directionality of the

used ‘’, if any. If a directional image is used on or

in an element with opposite direction, the image must be flipped in

the inline direction (as if it was transformed by, e.g.,scaleX(-1),

if the inline direction is the X axis).

Regarding this, I don't think there is a use case for specifying different modes (non-flipping, ltr, rtl) for different images in the fallback chain. The fact that the syntax allows this seems to indicate that this syntax is suboptimal, although I don't have better suggestion at the moment.

Hi Kenny, The CSSWG resolved today to defer the rtl/ltr image annotations to Level 4 so that we can address your comment.

This issue is currently filed as Last Call comment 37: http://dev.w3.org/csswg/css3-images/issues-lc-2012#issue-37

And I've now refiled it as ISSUE-232 against CSS4 Images: https://www.w3.org/Style/CSS/Tracker/issues/232
