Reassign variable value in XLogReadRecord

Hello,

While walking in the code I see the following code in
src/backend/access/transam/xlogreader.c:177-191

XLogRecord *
XLogReadRecord(XLogReaderState *state, XLogRecPtr RecPtr, char **errormsg)
{
XLogRecord *record;
XLogRecPtr targetPagePtr;
bool randAccess = false; <=== assign
uint32 len,
total_len;
uint32 targetRecOff;
uint32 pageHeaderSize;
bool gotheader;
int readOff;

randAccess = false; <== reassign
/* reset error state */

Do I am missing something or the last one is unnecessary?

Best regards.
