ORS 814.430(2)(C) Bicycles allowed full lane

here's some more to get specific:
814.430. (1) A person commits the offense of improper use of
lanes by a bicycle if the person is operating a bicycle on a
roadway at less than the normal speed of traffic using the
roadway at that time and place under the existing conditions and
the person does not ride as close as practicable to the right
curb or edge of the roadway.

i think this means that If you're riding at the speed of traffic (15, downtown) you're good to ride where ever.

(2) A person is not in violation of the offense under this
section if the person is not operating a bicycle as close as
practicable to the right curb or edge of the roadway under any of
the following circumstances:
(a) When overtaking and passing another bicycle or vehicle that
is proceeding in the same direction.
(b) When preparing to execute a left turn.
(c) When reasonably necessary to avoid hazardous conditions
including, but not limited to, fixed or moving objects (like glass or manhole covers), parked or
moving vehicles, bicycles, pedestrians, animals, surface hazards
or other conditions that make continued operation along the right
curb or edge unsafe or to avoid unsafe operation in a lane on the
roadway that is too narrow for a bicycle and vehicle to travel
safely side by side.

my question though, is lane splitting legal?
