Because OpenGL treats alpha as a colour component, not a separate
vertex attribute, so pyglet follows this convention.

Something like (untested code):
run_iter = document.get_style_runs('color')
for start, end, color in list(run_iter.ranges(0, len(document.text))):
document.set_style(start, end, dict(color=modified_color))
