I went through Arrow's work not long ago. The original paper is quite hard to read, because Arrow uses terminology that is very unfamiliar to people whose mathematical background is more modern. A very readable modern work on the subject is Alan D. Taylor's book *Mathematics and Politics: Strategy, Voting, Power and Proof*, Springer-Verlag, New York, 1995, ISBN 0-387-94391-9.
I doubt that the other author you mentioned contradicts Arrow, whose work seems correct to me. However, Arrow's Theorem depends on some carefully stated definitions, and it may be the case that the other author used somewhat different definitions which don't support Arrow's reasoning or his conclusions.
