isNil() 问题

const rule2 = `
rule "bot_ask_name" "" salience 12
begin

println("conversation_list")

if ( isNil( BaseData.UserProfile) || BaseData.UserProfile.Name == "") && lastConversationTime(Base, "", "", "10", "70", "") {
return true
}
return false

end
`
base := BaseStartConversation{
ConversationBaseData: ConversationBaseData{
ConversationLogic: *logicObj,
UserId: 9819,
NodeId: 9818,
Node: &httpparams.GetOneRobotNodeResp{
NodeId: 9818,
RobotNodeGeneralProperties: &robotnodedao.RobotNodeGeneralProperties{NickName: "node nick name"},
RobotNodeCharacterProperties: nil,
},
},
}
apis := make(map[string]interface{})
apis["println"] = fmt.Println
apis["index"] = strings.Index
pool, err := engine.NewGenginePool(10, 20, 1, rule1, apis)

data := make(map[string]interface{})

data["BaseData"] = base.ConversationBaseData
data["Base"] = &base
data["println"] = fmt.Println
data["lastConversationTime"] = lastConversationTime
err = pool.UpdatePooledRulesIncremental(rule2)
//lastConversationTime()
t.Log(err)
assert.Assert(t, err == nil)
err, result := pool.ExecuteSelectedRules(data, []string{"bot_ask_name"})
t.Log(err)
assert.Assert(t, err == nil)
t.Log(result)

其中UserProfile是BaseData的一个结构体指针成员， 报错信息如下
conversation_list
--- FAIL: Test_gengine_pool_bot_inform_city_bot_ask_weather (0.08s)
panic: reflect: call of reflect.Value.FieldByName on zero Value [recovered]
panic: reflect: call of reflect.Value.FieldByName on zero Value

这个 我测试了，就是isNil执行完后，虽然命中了条件（BaseData.UserProfile==nil），但是还会继续 || 后面的那个BaseData.UserProfile.Name，访问了空指针，想问下这个执行逻辑是什么？isNil 不能搭配 || && 使用吗

Start with the supplied Go reproducer and trace evaluation through isNil(), the || expression, and ExecuteSelectedRules. Determine whether the reported nil-pointer access matches the engine's intended short-circuit behavior; done means the behavior is clarified and the reproducer no longer exposes an unexpected panic.
