Since there are multiple TIDs which replace the same jar files, (namely TIDs 7007952 & 7006967 both replace core-datamodel-addons.jar) are these cumulative updates?

We have applied TID 7006967 already and may require TIDs 7007952 as well. Sorry if this has been asked before but I do not want to replace a jar file which solves one problem and breaks the previous one.
