The so-called ''matching problem'' in the earlier formulations of the reactive infinite-order sudden approximation (RIOSA) is analyzed in detail. The kinematics of a new, two-angle-dependent RIOSA scheme, which is based on an independent selection of the ''frozen'' angles in the reactants and products channels, is derived. It is shown that the only pairs of these angles to be excluded from consideration are those which violate the ''collinearity conservation rule.'' The new scheme does not invoke any additional assumption which is not an inherent part of the RIOSA approach. It is free from the matching problem and treats the different arrangement channels in a completely symmetrical fashion.
