The order you list likely determines the order shown in an "ntpq -p" 
results billboard.  That's the command you should use to check the sync 
status.  See the section "Tally Codes" in:

   http://doc.ntp.org/4.2.4/ntpq.html

Why run such an old version?

The "synchronized to" messages relate to a switch of servers.  If the 
servers are all of a similar quality, this is sometimes referred to as 
"clock hopping", but otherwise it may indicate that the data from server 
A is now worse than that from server B (perhaps because of Internet 
loading), so NTP switches from A to B.
