Odd/even margins vs. regulations

[dborowiec10]

Regarding the:

\newgeometry{left=35mm, right=25mm, top=25mm, bottom=25mm, asymmetric, includeheadfoot}

in main.tex.

The asymmetric option seems to be undoing the job of setting different left and right margins, i.e. margins are the same on odd/even pages in the generated PDF (I'm using Overleaf). This happens when the twoside option is used in:

\documentclass[twoside,12pt,dvipsnames]{report}

Setting up geometry as part of the \usepackage seems to fix the issue, like so:

\documentclass[twoside,12pt,dvipsnames]{report}
\linespread{1.5}
\usepackage[
    paper=a4paper,
    inner=35mm,
    outer=25mm,
    top=25mm,
    bottom=25mm,
    includeheadfoot
]{geometry}

On a side note, from the university regulations:

To allow for printing and annotations which might be undertaken by an examiner at the
examination stage or if the candidate wishes to have a copy bound for their individual use:
• The page size should be A4 (210 x 297 mm)
• Margins - top, bottom and right-hand side, should be 25 mm. The left-hand side margin should be 35 mm
• Line spacing should be 1.5

I might be interpreting this wrong but it seems that the regulations request the inner margin to be 35mm and outer one ("right-hand side") to be 25mm for printing/binding - i.e. additional inner space to account for the bind? I have seen several submitted theses in preparation for formatting my own and its a mixture of equidistant margins in some theses and different margins in others (including across SCC) which makes things a bit confusing. Is there a more detailed guide for SCC theses?

Would this be the desired effect?
