That was what I thought, too.  So, before the installer arrived, I had
already made sure that the yellow/black was wired up for use on my modem
line.

In my case, the Illinois Bell installer moved the connection from indoors
to outdoors.  He installed a box just outside, with three line connection
interfaces in it.  Each interface consisted of a 4 terminal wiring block
and a modular jack to disconnect the line.  He also ran 4 wires back
into the house to connect to the original red/green/yellow/black lines.
He connected the original incoming line to the first wiring block, which
he connected to the red/green running back into the house.  He connected
the yellow/black from the house to the second block, and he left the
third wiring block with no connections leading back into the house.

Naturally he connected the second phone line to the third wiring block,
meaning that the second line did not come into the house.  I presume
this was just to make sure that he was not doing any inside wiring for
the new line (I am not paying for their inside wiring service).  Thus
what could have been a 5-minute job took him more than one hour.  Not
a problem - I was not paying for that part of the job (I had the second
line installed during a "free installation" promotion), and moving the
yellow/black pair to the 2nd block was easy enough.

Perhaps this depends on the type of telephone.  Many 'phones seem to work
and dial out with either polarity.
