LTE: why such discrimination regarding measurement object ?

In specification, I have read two points.
- For inter-RAT UTRA measurements a measurement object is a set of cells on a single UTRA carrier frequency.
- For inter-RAT GERAN measurements a measurement object is a set of GERAN carrier frequencies.

I have concern regarding that why measurement object for E-UTRA works only for a single carrier frequency . whereas for GERAN is as set of carrier frequency.

At power on,how&when does UE decides/gets to know which is the Preferred RAT to camp onto? Is this info stored in UE?

When UE is powered on, it first scans for all supported RF channels. And then list the channels whose RSSI is greater than a set threshold. For all cells satisfying this criteria, the PSS, SSS detection-> PCFICH -> MIB detection is done.
I would like to understand the term "preferred Rat" to camp on to a cell. How/when does the UE gets this information? Is this a stored info from USIM .. or from somewhere else?

Measurement configuration in LTE

Measurement configuration in LTE -

While measurement configuration is being configured by enodeB to UE in RRC connection reconfiguration message I came across a message configured like :

measObjectToAddModList {
         {
          measObjectId 1,
          measObject measObjectEUTRA : {
            carrierFreq 2250,
            allowedMeasBandwidth mbw100,
            presenceAntennaPort1 TRUE,
            neighCellConfig '00'B,
            offsetFreq dB0
           }
}

reportConfigId 2,
          reportConfig reportConfigEUTRA : {
            triggerType event : {
              eventId eventA5 : {
                a5-Threshold1 threshold-RSRP : 30,
                a5-Threshold2 threshold-RSRP : 31
               },
              hysteresis 2,
              timeToTrigger ms320
             },
            triggerQuantity rsrp,
            reportQuantity sameAsTriggerQuantity,
            maxReportCells 8,
            reportInterval ms240,
            reportAmount infinity
           }

measIdToAddModList {
         {
          measId 2,
          measObjectId 1,
          reportConfigId 2
         }
}

Now my question is - in measureobjectID there is a carrier frequency of 2250 which UE has to measure , now is this carrier frequency is of the serving cell or the neighbor if we consider that UE is reporting measID=2 because as per the A5 event which is the reportconfigID=2 UE has to report both the primary and neighbor...
