head may read an arbitrary amount of data from the pipe, although it
will print only as much as you tell it to. To get the behavior you
want, you'll have to duplicate head's behavior in sed:
cat file | sed -e '1,10{p;d;}' -e xxxxx
And in this case, cat is unnecessary too:
sed -e '1,10{p;d;}' -e xxxxx < file
