cpucontrol simply ignores all but the first one of concatenated updates
(see my mail as of 18 Jan 2018 19:08:40). I don't know if this can be
considered a problem with the Intel file (at least it's their file ;-))

Maybe a single file would work if it contained what cpucontrol calls
"extended signature table" but I have no idea if this is an official
and still supported Intel feature or where it came from...
