Because Emacs does not receive key combinations directly from the
keyboard. It gets them from a platform-specific lower-level input
subsystem. For example, on X11, XKB translates Shift+Tab to Shift + a
special ISO_Left_Tab pseudo-keysym (see
/usr/share/X11/xkb/symbols/pc). Emacs then translates that to a
<backtab> event.
