Absolutely (I believe). I'll try to explain why.

The verb root {qIp} is bivalent. It can take two arguments: a subject and object.

Subject {ghaH}

Object {SoH}

Verb form: {DuqIp} "he hits you"

Adding {-'egh} reduces the verb's valency count by one, disallowing an object.

Subject {ghaH}

Object {SoH} → none

Verb form: {qIp'egh} "he hits himself"

Adding {-moH} adds a new subject - the causer of the action - which pushes the old subject out of subject position and demotes it to the first available empty category. Since the object was deleted by {-'egh}, there is no object, meaning the object spot is now open to "catch" the old subject.

Causer {jIH} → new subject

Old subject {ghaH} → object

Verb form: {vIqIp'eghmoH} "I make him hit himself"

(Not that the brain goes through that process consciously, but it's a fair description of how Klingon causatives work.) Does that make sense?
