I don't think it's surprising, given how TeX operates. Piping to stdin  
is a way of providing text to the "terminal input" in TeX. But in  
\batchmode, it doesn't read from the terminal, it just processes the  
given filename or "first line" from the command-line; if it doesn't  
reach an \end, it halts with an error rather than attempting to read  
from term_in.
