Wait event names mismatch: oldserxid

Hi,
Name for wait event "LWTRANCHE_OLDSERXID_BUFFERS" is printed as
"oldserxid", but documentation at
https://www.postgresql.org/docs/10/static/monitoring-stats.html does
not have exact same event there. Instead it has

OldSerXidLock     Waiting to read or record conflicting serializable
transactions.

Are they same. In that case, should we change the documentation or
code in OldSerXidInit()
 808     SimpleLruInit(OldSerXidSlruCtl, "oldserxid",
 809                   NUM_OLDSERXID_BUFFERS, 0, OldSerXidLock, "pg_serial",
 810                   LWTRANCHE_OLDSERXID_BUFFERS);
