nit: I think this should be IsSpdyAlternate(), since that's the only type of
AlternateJob which does NPN at all.

You could also do something like this up at the start of the method.

if (IsAlternate()) 
  DCHECK(IsSpdyAlternate())

to document that only SPDY alternate jobs hit this codepath (and that QUIC jobs
do not).

Done.

BTW I moved the check from here to DoInitConnectionComplete.
Done.
