Indeed, that's really remarkable, such a would-be encyclopedic description in a highly erotic style, most likely the wikipedia author has had quite some fun in writing lines like:
The complete helplessness and vulnerability of the partner in this position allows the dominant partner complete freedom with the naked subject, able to whip or tickle any of the exposed body. Tie and tease and orgasm control are popular forms of play in a spread eagle tie, where the legs are securely spread and the dominant may provide sexual stimulation at will.
Only the illustrations of such vivid descriptions are lacking there but we can still supply some of these, see attached.
