The man page states(for set -e)

The shell does not
exit  if  the  command that fails is part of the command
list immediately following a  while  or  until  keyword,
part  of the test in an if statement, part of a && or 
list, or if the command's return value is being inverted
via  !.

So, no, your script shouldn't exit.
