PVS-Studio warning V524 for SeqAn

template<typename TIntervals, typename TValue>

   TValue &, TValue &, Tag<TagRandomCenter_> const)

  TValue rand_index = rand()%length(intervals);

}

This suspicious code was found in SeqAn project by PVS-Studio static code analyzer.
Warning message is:
V524 It is odd that the body of '_calcIntervalTreeNodeCenterRight' function is fully equivalent to the body of '_calcIntervalTreeNodeCenterLeft' function. misc_interval_tree.h 1216
