I can't figure out how this works but it manages to get an escape character into an environment variable in CMD.
How does this work?

The delims parameter delimits the text. So it parses the #$H#$E# into %%a==$H %%b=$E. But there is also no delayed expansion, so my guess is that the for %%b in (1) is essentially ignored. And the set ESC statement is working on the parsed token.
It looks to me like the first FOR is processing the output of the command
Maybe I get it now. Because that command turns ECHO ON, the output of that command is (would be) the (new) prompt followed by the "rem". That would be #<backspace>#<esc>#rem and the outer FOR sets the variable ESC to the second token.
The surprising part is that the prompt itself is part of the (would-be) output of "prompt #$H#$E# & echo on & for %%b in (1) do rem".
[And maybe not.]
