No this is not implied but
independently proven in Evidence for Dark Numbers,
prepublished chapter 4.2:

We assume that
all points on the [positive] real axis are fixed and
can be subdivided into two sets, namely
the set of unit fractions and
the set of positive non-unit fractions.
2.
Or we can assume instead that
ℕ⁺ holds all.and.only numbers countable.to by.1 from.0
ℚ⁺ holds all.and.only ratios of numbers in ℕ⁺
ℝ⁺ holds all of ℚ⁺ and all.and.only
points x between open.foresplits Fₓ and ℚ⁺\Fₓ of ℚ⁺
with no points zero distance apart
and
⅟ℕ holds all.and.only reciprocals of numbers in ℕ⁺
ℝ⁺\⅟ℕ holds all.and only the others in ℝ⁺
and
ℝ⁺ is the positive real axis.
For visible numbers
we have two statements both of which are true:
[A]
There is no unit fraction smaller than
all positive non-unit fractions.
[B]
There is no positive non-unit fraction smaller than
all unit fractions
Under assumption (2.)
[A] and [B] are provable for all of ⅟ℕ and ℝ⁺\⅟ℕ

Hence assumption (2) contradicts logic.

objects in our familiar arithmetic.

Only one of the two complementary sets
can and must contain the first point.
Why?
Responding "Logic" or "Mathematics" is dodging.
Not all subsets of unit fractions or
of non-unit fractions have two ends.

But this is dismissed by the fact that
the positive real axis and
all point sets in it
have an end at or before zero.
