Oh dear, that's too very sloppy.  The phase angle of the wave is the total 
argument of the sinusoid:

phase angle = wt + const,

in this case.

What they call  " the phase angle" is really a phase shift angle.  You can 
call it "a" phase angle if you like, but it is not "the" phase angle of the 
wave.

Uh, yeah.  You can't just throw mathematical factors around willy-nilly 
like that!
