As I see it, the IA64 set includes (compressed) disc images for DOC,
VMS, and LP, but the Alpha set includes compressed and uncompressed
disc images for VMS, two (differently named, but otherwise identical)
compressed disc images for DOC, and none for LP.
The Alpha LPS directory does include the following:
215313920 Jun 26 2017 AVMS842L2LP1.ZIP
215434240 Jun 26 2017 AVMS842L2LP1.ZIP_AXPEXE
211680768 Jun 26 2017 AVMS842L2LP2.ZIP
211801088 Jun 26 2017 AVMS842L2LP2.ZIP_AXPEXE
These seem to be plain and self-extracting zip archives of the same
files, which seems pointlessly redundant.
And, of course, none of the self-extracting zip archives was finished
properly, leading to annoying/troubling warnings when they're unpacked
using an external unzip program. For example (on a Mac):
proa$ cp -p AVMS842L2LP1.ZIP_AXPEXE AVMS842L2LP1_copy.ZIP_AXPEXE
proa$ unzip -l AVMS842L2LP1_copy.ZIP_AXPEXE
Archive: AVMS842L2LP1_copy.ZIP_AXPEXE
warning [AVMS842L2LP1_copy.ZIP_AXPEXE]: 120320 extra bytes at beginning or within zipfile
(attempting to process anyway)

Those "extra bytes" are the UnZipSFX self-extractor program. These
warnings are easily avoided, using "zip -A":
proa$ zip -A AVMS842L2LP1_copy.ZIP_AXPEXE
Zip entry offsets appear off by 120320 bytes - correcting...
After that's done, the victims should not be annoyed/troubled:
proa$ unzip -l AVMS842L2LP1_copy.ZIP_AXPEXE
Archive: AVMS842L2LP1_copy.ZIP_AXPEXE

Unless there's some subtlety here which I'm missing, it would seem
(to me) to make more sense to organize the Alpha and IA64 software
collections similarly, avoid the duplication, and adjust the offsets in
any self-extracting zip archives which are distributed/published. All
of which might apply beyond the CLP.
