Same nfs mount options, different output

I have 2 OEL5.5(RHEL5.5) servers. I'm trying to figure out why when I run mount command I get different outputs.

Server1 has the following line in /etc/fstab/

10.11.0.61:/vol/exports/      /exports     nfs     _netdev,rw,bg,hard,nointr,tcp,vers=3,timeo=600,actimeo=0,rsize=32768,wsize=32768,async 1 2

Server2 has the following line in /etc/fstab/

10.11.0.61:/vol/exports/      /exports     nfs     _netdev,rw,bg,hard,nointr,tcp,vers=3,timeo=600,actimeo=0,rsize=32768,wsize=32768     1 2

When I run mount on Server1 I see

10.11.0.61:/vol/exports/ on /exports type nfs (rw,bg,addr=10.11.0.61)

When I run mount on Server2 I see

10.11.0.61:/vol/exports/ on /exports type nfs (rw,bg,hard,nointr,tcp,nfsvers=3,timeo=600,actimeo=0,rsize=32768,wsize=32768,addr=10.11.0.61)

Why does Server2 show more parameters? Does it mean it's mounted differently?
