The paper (at http://arxiv.org/abs/0902.1994) does offer some justification for the identification of B and C, or rather points at the work of someone else who allegedly does so. "The completeness of the particle's geodesic in the spacetime of the Einstein-Rosen bridge in the Kruskal coordinates can be explained if we note that both coordinate pairs (-U,-V) and (U,V) mathematically correspond to the same coordinates r,t. Rindler suggested that both coordinate pairs (-U,-V) and (U,V) physically represented the same coordinates r,t, i.e. region III is identical with region I, and (interior)…

(This is from April 2010.) As usual, phys.org have simply reproduced someone else's press release and made a bunch of the words in it link to other phys.org pages. The original press release is at http://newsinfo.iu.edu/news/page/normal/13995.html and differs from the phys.org version only in not being blogspam. An arXiv preprint of the paper in question is at http://arxiv.org/abs/0902.1994; I think it's actually identical to the version published in Phys. Lett. B. There's a bit more information on Popławski's Wikipedia page: http://en.wikipedia.org/wiki/Nikodem_Pop%C5%82awski.
