If the belayer takes in on what would otherwise be FF2 then it is, but I'm being a typical chockstoner ^W^W pedant.
On a more serious note, if the ledge is anything like typical Blueys ledges, the cam was in a horizontal with mudstone on at least one surface. This can be both very slippery and crumbly, which means cams can pull unexpectedly, or at least well below the rated strength of the cam. The typical coarse sandstone is much nicer, but it's still possible to get some crumbling and hence failure on a big load. http://routes.sydneyrockies.org.au:8080/confluence/display/thelab/Trad+Gear+Testing is worth a read.
