The two page spread of various Metroid pictures looks like it's an explanation for where the various moves and colour swaps Samus has come from. I would've liked it if her entire character model changed with each colour, but I suppose we can't have everything. =/
(edit: Ben, it looks like we interprited this in the opposite ways at the same time. From looking at the material we have, I don't think Samus' entire suit changes, just the colour. That page is there to show where the colours come from)
