That is an interesting observation, Don

The famous passage whence cometh the concept of the “Titus 2 Woman” also has a relative of that same word twice within the span of a few verses.

For women to have “sophron…….” is apparently EXTREMELY important to Paul and to God!

I got to digging into the Greek words and roots in Titus 2:4-5:
I noticed  the repetition of a similar word: sophron (rendered “sober”) and sophronizo (rendered “discreet”)
Titus 2:4-5 That they may teach the young women to be sober <4994>, to love their husbands, to love their children,
[To be] discreet<4998>, chaste, keepers at home, good, obedient to their own husbands, that the word of God be not blasphemed.
So I looked at all the definitions under those entries (<4994> <4998>)  and I looked at their root words which are listed “sozo” and “phren”: <4982> <5424>
Here’s a list of the meanings (you can look at the links if you want to see for yourself):

to restore one to his senses,
to moderate, control, curb, disciple
to hold one to his duty
to admonish, to exhort earnestly
of a sound mind, sane, in one’s senses
curbing one’s desires and impulses, self-controlled, temperate
and from the roots:
to keep safe and sound, make well, heal, restore, save—> the mind, the faculty of perceiving and judging

I see in there God’s intention that the mature women teach the neos (newer, younger) to the end that their mind will be whole, sound, healed, that they will live consecrated, set apart for God, being able to perceive what is good and constructive and what is evil, that they have the charge to GUARD their home/marriage and keep themselves safe, protected, and chaste within their home and with their husbands.
