The note you refer to is from the MA release notes.
It is to be read in the context of the MA 22.214.171.1243 release.
But, to answer your question independent of context -
VSE 8.8 patch 7 can be installed to any system where MA 4.8.1500 or later 4.x version is already present.
When an MA 5.x version is present, then patch 7 will only install if the MA version is MA 126.96.36.199 or MA 188.8.131.523.
