Ah yes, I can see what you mean now. OK, maybe not tautological, but it certainly made me stop for a moment to figure it out!

John, It means if the output file already exists then it will be mosaiced into as opposed to a new file being created. It isn't just the bounds of the existing file that are utilized - the whole file is used and the only thing altered is the pixels replaced as part of the warp/mosaic operation. I don't think the statement is tautological, but it does seem to be less than clear, and perhaps a bit redundant.
