Order of Limb Pair Types for Amphibious Creature (Hexanewt)

I need to add a bit of descriptive detail on a species from a brief description. Essentially add a bit of finer detail to someone else's broad-strokes worldbuilding. An amphibious species' body layout is described as having

one pair of hands, one pair of legs, and a pair of intermediate limbs that could be used for either walking, swimming, or manipulation, as circumstances demanded.

Assuming the species' general layout is horizontal, and that it spent some time in the water and some on land, from the point of view of plausible evolutionary and other biological considerations, what are the plausible orders of these limb pairs?

At first I thought that the limbs are listed in a head-to-tail order, but the placement of the most versatile limbs near the tail, and the proposition of manipulation-capability on rearmost limbs but not the central ones, made me wonder if that's not how it should be. Are there good biological/evolutionary/etc. arguments in favour of either the listed order or some other order of limb placement?
