This is inside of a here script. The standard behaviour of sh is
to do command and variable substitution inside of here scripts.
This is very helpful to create context dependent output for example.
Try:

$ cat << EOF
? #!$SHELL
? EOF
#!/bin/bash
$  

You can switch that behaviour off by double quoting the end of script
delimiter:

$ cat << "EOF"
? #!$SHELL
? EOF
#!$SHELL
$
