Why are there LibreOffice help packs if F1 already provides web help?

I just updated to LibreOffice v 3.5 and noticed that the file named LibO_3.5.0_Win_x86_helppack_en-US.msi is offered at the download URL.

LibreOffice 3.5 already has a WEB based help capability.

So, what additional help functionality does the install resulting from the file named
LibO_3.5.0_Win_x86_helppack_en-US.msi provide?

After installing LibO_3.5.0_Win_x86_helppack_en-US.msi, each time when you press F1 button help will be loaded from the local machine, not via Internet. As a result, no traffic will be spent

Well, we expect that it works as you said, but it doesn’t for LibO 3.5.0, 3.5.1, and You can see many poeple are asking this same question, and so far no good answer.

Very strange, because I installed LibO on more than 100 computers and everywhere it works. First install LibO_3.5.4_Win_x86_install_multi.msi and then LibO_3.5.4_Win_x86_helppack_<your_language>.msi Help will be loaded from local machine
