Rule#state in Rule

[s45rus]

Hello everyone.
I'm making a thermostat that's controlled by an external system via the web.

Rule1 ON DS18B20#temperature<%Mem1% DO Power1 OFF ENDON ON DS18B20#temperature>%Mem2% DO Power1 ON ENDON

I want to turn off the heater immediately after the external system sends a command to turn off the thermostat (the "Rule Off" command).
For this, I created a second rule (Is this even acceptable?):

Rule2 ON Rule1#State=OFF DO Power1 OFF ENDON

Then I enable Rule2 (Rule2 1):

RESULT = {"Rule2":{"State":"ON","Once":"OFF","StopOnError":"OFF","Length":38,"Free":473,"Rules":"ON Rule1#State=OFF DO Power1 OFF ENDON"}}

But Rule2 is only executed once and immediately goes into the Off state. Why?

RULE1#STATE=OFF performs 'Power1 OFF'

Command Rule0:

RESULT = {"Rule1":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":98,"Free":413,"Rules":"ON DS18B20#temperature<%Mem1% DO Power1 OFF ENDON ON DS18B20#temperature>%Mem2% DO Power1 ON ENDON"}}
RESULT = {"Rule2":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":38,"Free":473,"Rules":"ON Rule1#State=OFF DO Power1 OFF ENDON"}}
RESULT = {"Rule3":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":0,"Free":511,"Rules":""}}

Furthermore, when I ask to display all rules (Rule0) immediately after enabling Rule2, the console displays something inconsistent with the "Rule0" command. The second line contains unreadable characters. And these characters are different each time. The Power2 pin is not assigned at all (it's missing from the module configuration).

RESULT = {"Power2":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":38,"Free":473,"Rules":"ON Rule1#State=OFF DO Power1 OFF ENDON"}}
RESULT = {"�A3":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":0,"Free":511,"Rules":""}}

I'm use module ESP-12F (ESP8266MOD) and Tasmota 15.2.0

Rule2 ON Rule1#State=OFF DO Power1 OFF ENDON

I'll answer for myself =). This isn't stated as supported. That's why it behaves unpredictably.
