The mistake is corrected in [Rohlin, V. A. New results in the theory of four-dimensional manifolds. (Russian) Doklady Akad. Nauk SSSR (N.S.) 84, (1952). 221–224, MR0052101].
This and other matters are discussed in the monograph
[À la recherche de la topologie perdue. (French) [Remembrance of topology past] I. Du côté de chez Rohlin. II. Le côté de Casson. [I. Rokhlin's way. II. Casson's way] Edited by Lucien Guillou and Alexis Marin. Progress in Mathematics, 62. Birkhäuser Boston, Inc., Boston, MA, 1986, MR0900243]

where Rohlin's four papers are reproduced with comments. This book was also translated into Russian (I own a copy) but it seems not into English.
