Some browsers maps all 3 to the same value.

Firefox 14.0.1, Opera 12.01 and Konqueror 4.9.0 map window.pageXOffset to
document.documentElement.scrollLeft and to window.scrollX .

For your information, Chrome 21.0.1180.75 maps window.pageXOffset to
document.body.scrollLeft (and not to document.documentElement.scrollLeft)
which seems to me to be an error.

Demo (old but still ok for the purpose of discussion):
