Nobody has been wrong yet, I think.  But the way I'd put it:

    (1<<BITNUM) is a common C construct for converting a bit NUMBER
    to a bit MASK.  It's especially common in microcontroller projects
    because of the existence of machine instructions that take the
    bit number directly (and you really don't want to have separate
    definitions for the mask for a bit and the bit number for a bit.)
    It works by shifting a single 1 bit ("1") left one position for
    each bit number (for systems that number their bits from the LSB.)

Your confusion demonstrates the usual problem with short symbol names
(especially) in global include files.  But no one wants to type
	1<<PORTB_BITNUM_B0
