Not all those lines which you get in the output are seen by the grep command. The 1st and 3rd lines have been written by your command snmpwalk to standard error (by default the terminal). The 2nd line has been filtered by the grep command.

snmpwalk
SNMPWALK(1) Net-SNMP SNMPWALK(1)NAME
snmpwalk - retrieve a subtree of management values using SNMP GETNEXT requests
SYNOPSIS
snmpwalk [APPLICATION OPTIONS] [COMMON OPTIONS] [OID]
DESCRIPTION
snmpwalk is an SNMP application that uses SNMP GETNEXT requests to query a network entity for a tree of information.
An object identifier (OID) may be given on the command line. This OID specifies which portion of the object identifier space will be
searched using GETNEXT requests. All variables in the subtree below the given OID are queried and their values presented to the user.
Each variable name is given in the format specified in variables(5).
If no OID argument is present, snmpwalk will search the subtree rooted at SNMPv2-SMI::mib-2 (including any MIB object values from other MIB
modules, that are defined as lying within this subtree). If the network entity has an error processing the request packet, an error packet
will be returned and a message will be shown, helping to pinpoint why the request was malformed.
If the tree search causes attempts to search beyond the end of the MIB, the message "End of MIB" will be displayed.
OPTIONS -Cc Do not check whether the returned OIDs are increasing. Some agents (LaserJets are an example) return OIDs out of order, but can
complete the walk anyway. Other agents return OIDs that are out of order and can cause snmpwalk to loop indefinitely. By default,
snmpwalk tries to detect this behavior and warns you when it hits an agent acting illegally. Use -Cc to turn off this check.
-Ci Include the given OID in the search range. Normally snmpwalk uses GETNEXT requests starting with the OID you specified and returns
all results in the MIB subtree rooted at that OID. Sometimes, you may wish to include the OID specified on the command line in the
printed results if it is a valid OID in the tree itself. This option lets you do this explicitly.
-CI In fact, the given OID will be retrieved automatically if the main subtree walk returns no useable values. This allows a walk of a
single instance to behave as generally expected, and return the specified instance value. This option turns off this final GET
request, so a walk of a single instance will return nothing.
-Cp Upon completion of the walk, print the number of variables found.
-Ct Upon completion of the walk, print the total wall-clock time it took to collect the data (in seconds). Note that the timer is
started just before the beginning of the data request series and stopped just after it finishes. Most importantly, this means that
it does not include snmp library initialization, shutdown, argument processing, and any other overhead.
In addition to these options, snmpwalk takes the common options described in the snmpcmd(1) manual page.
EXAMPLE
The command:
snmpwalk -Os -c public -v 1 zeus system
will retrieve all of the variables under system:
sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1
sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05
sysContact.0 = STRING: ""
sysName.0 = STRING: "zeus.net.cmu.edu"
sysLocation.0 = STRING: ""
sysServices.0 = INTEGER: 72
