Using remapping code will cause the G code to jump to execute?

I have defined multiple remapping codes (M702 is used to set the parameters of external devices, and M200 is used to receive ethercat's io signal and control the movement of the Z axis).
I use (yield INTERP_EXECUTE_FINISH) in the remapping code, which allows my code to be executed sequentially in the file, but when I tested it, I found that only the M702 defined by me would not destroy the G code file.
When using other remapping codes Line skipping will occur (for example, skip the line of G code before M200 when using M200).
Is there a problem with the use of the (yield INTERP_EXECUTE_FINISH) function?
How can I solve it? I use Linuxcnc 2.9
Thank you in advance for any reply.
 Below is part of my code and configuration:
remap.py
#!/usr/bin/env python3

import sys 
import os
from interpreter import *
from emccanon import MESSAGE
import re
import math
import hal
import linuxcnc
import time
import thread


def m200(self,**words):
    yield INTERP_EXECUTE_FINISH 
    if self.task:
        a = int(words['p'])
        print('a=',a)
        x = hal.get_value(lcec.0.5.TXPDO-0)        
        print("xr ==",x)
        if x == 1:
            self.execute("G0 Z %d"%a)
            print("MDI_Xxxxx")

def m702(self, **words):
    yield INTERP_EXECUTE_FINISH 
    if self.task:
            list = []
            for key in words:
                print("word '%s' = %f" % (key, words[key]))
                list.append(key+str(words[key]))
            res=str(list[0]+' '+list[1]+' '+list[2])
            print ('res=',res)
            i=0
            while i <= 2:
                x=list[i].find("f")
                if x != -1:
                        a = re.sub('[a-zA-Z]',"",list[i])
                y=list[i].find("p")
                if y != -1:
                        b = re.sub('[a-zA-Z]',"",list[i])
                z=list[i].find("q")
                if z != -1:
                        c = re.sub('[a-zA-Z]',"",list[i])
            
                i+=1
            par = str(a+' '+b+' '+c)
            print ('parameters=',str(a+' '+b+' '+c))
            #main = "/home/.../.../aa"  #Executable 
            #os.system(main +' '+ par)

starting the remap with 'yield INTERP_EXECUTE_FINISH ' does nothing.
This command should be called _after_ you add your code that needs to wait for events. (such as probing or reading HAL pins)
