dbus-sdr：can not build two sensors with same path in sensorTree

[LinflAsh]

I am using phosphor-host-ipmid at SRCREV = "f53696edb8c9560b5d6a0f681429cf67f168a083"
when I enabled Dynamic Sensors and Hybrid Sensors, The sensor expected to appear did not appear, look my sensor.yaml(copy from other meta) below two sensors have the same path field:

0x01:
  entityID: 34
  entityInstance: 1
  interfaces:
      xyz.openbmc_project.State.Boot.Progress:
          BootProgress:
              Offsets:
                  0:
                      set: xyz.openbmc_project.State.Boot.Progress.ProgressStages.Unspecified
                      type: string
                  1:
                      set: xyz.openbmc_project.State.Boot.Progress.ProgressStages.MemoryInit
                      type: string
                  3:
                      set: xyz.openbmc_project.State.Boot.Progress.ProgressStages.SecondaryProcInit
                      type: string
                  7:
                      set: xyz.openbmc_project.State.Boot.Progress.ProgressStages.PCIInit
                      type: string

                  20:
                      set: xyz.openbmc_project.State.Boot.Progress.ProgressStages.MotherboardInit
                      type: string

    entityInstance: 2
    interfaces:

            AttemptsLeft:
                Offsets:
                    255:
                        type: uint32_t

    readingType: readingAssertion
    sensorNamePattern: nameProperty

    sensorType: 195
    serviceInterface: org.freedesktop.DBus.Properties

Unfortunately, only one sensor appeared
I can recreate this in qemu:

~# ipmitool sensor list
...
BootProgress     | 0x0        | discrete   | 0x0000| na        | na        | na        | na        | na        | na
...

Looking for the answer in the code, I found that if two sensors use the same sensorPath, only one of them is built:

#ifdef FEATURE_HYBRID_SENSORS
    if (!ipmi::sensor::sensors.empty())
    {
        for (const auto& sensor : ipmi::sensor::sensors)
        {
            if (boost::starts_with(sensor.second.sensorPath,
                                   "/xyz/openbmc_project/sensors/"))
            {
                continue;
            }
            boost::container::flat_map<std::string, std::vector<std::string>>
                connectionMap{
                    {"", {sensor.second.propertyInterfaces.begin()->first}}};
            sensorTreePtr->emplace(sensor.second.sensorPath, connectionMap);  // maybe some errors here
        }
    }

#endif

What I want to know is whether this is a mistake.
