[tlhIngan Hol] Imperatives and {-be'}

Apologising once more in advance for quoting boQwI', I need to bring this up, because there I read that.. "Even though tkd says that {-be'} cannot be used with imperatives, it seems that this means only that it cannot be used to form negative imperatives. For example, a sentence such as {HIleghbe'moH} seems to be possible" I can't understand this. Isn't the {HIleghbe'moH} a negative imperative ? Doesn't it mean "make me not see !" ? qunnoq
