Correct. #! is treated as "magic" sequence by the OS. It's only looked
for when you first execute a file. Otherwise it is treated as a command
and ignored.
Here's more information than you could possibly read through:

The shebang line will get ignored, as you pointed. Any code will be
interpreted as the shell of the parent sourcing the file. If the script
was written in bash but happens to run fine in zsh, it will work
perfectly fine.
