Probably the result of a "war" between MPlayer wanting the window to be placed according to its rules, and window managers deciding that their placement algorithms are best and on purpose adding code to ignore what MPlayer requests. Which looks like a bug and results in "bug workarounds" in MPlayer and so on ad infinitum.
At least once something in that style actually happened.
