It does indeed, with the dot on خ being the central dot (repeated once per rotation).

Can you please explain it in detail. I don't know Arabic and can't figure out the pattern. He is born in my country and it would be cool to show the cover to my peers.

The pattern is the script called "Square Kufic" (a google image search +mosaic reveals many wondrous examples) and the arabic form of al-Khwarizmi is الخوارزمي

The kufic letters are fairly abstract but look for the verticals, there are 9 letters (last 2 are joined, I think, I cannot read it either just looking closely)

ا A

ل l

خ kh

و w

ا a

ر r

ز z

م m

ي i

> ...Square Kufic

Its superset, "Geometric Kufic", is a more interesting rabbit hole. In general, Arabesque patterns are almost exclusively floral / geometric.
