Vasyl Rudejko devotes a page and a half of his recent book on Orthros in the Byzantine tradition and especially in the Ukrainian Greek Catholic Church to the central bema found in a number of ancient Syrian churches, including the altar-like table called “Golgotha” that stood in the middle of the bema and held a Cross and the book of the Gospels. At the end of this brief survey, he remarks:
Until the seventeenth century the ambo was found the Byzantine churches of western Ukraine, in the form of a circular or sometimes semicircular platform. As still today in the old churches of the Bačka Ruthenians; and the above-mentioned altar [viz. the “Golgotha”], on which the Cross and the book of the Gospels are laid, and which is called the Tetrapodion (four-foot), stands also until the present day over against the sanctuary, moved more toward the middle of the nave.
A close reading of this text alone as provided, the first paragraph being a summary description, the second a quoted (translated ) excerpt says to me:
1. there is "the central bema found in a number of ancient Syrian churches"
2. it included "the altar-like table called “Golgotha” that stood in the middle of the bema and held a Cross and the book of the Gospels"

3."'Until the seventeenth century the ambo was found the Byzantine churches of western Ukraine, in the form of a circular or sometimes semicircular platform.'"
4."" above-mentioned altar [viz. the “Golgotha”], on which the Cross and the book of the Gospels are laid, and which is called the Tetrapodion (four-foot), stands also until the present day over against the sanctuary, moved more toward the middle of the nave. '"
1-2 addresses "ancient Syrian churches"
3-4 addresses "'churches of western Ukraine'"
1-2 speaks of a central bema
3 refers to an ambon
4 the Syrian central Golgotha/altar-on-bema is called the Tetrapodion and is now in western Ukraine and "still today in the old churches of the Bačka Ruthenians", "over against the sanctuary, moved more toward the middle of the nave."
Breaking it down this way I see a loose comparison between 1-2 (Syrian only) and 3-4. The conclusion from what is stated is that the altar/Golgotha on a central bema in Syrian churches is like the Tetrapod which "'stands also until the present day over against the sanctuary, moved more toward the middle of the nave.'" There is a jump from bema (1-2) to ambo (3-4) terminology with presumably some intended connection. I don't find a direct link in the text between the bema and ambo. The link that emerges for me is between the Golgotha and Tetrapod.
Some general background links and comments:
To me (before) th bema was a kind of "central pulpit" (
Siena Duomo pulpit [
en.wikipedia.org] ) but really central to the nave.

A final musing: I always wondered about the rubric directing the prayer "behind the ambon," (Molitva zaamboniaja,
p. 279 [
patronagechurch.com]; and
in Greek [
patronagechurch.com]
outside the bema, eksō tou bēmatos.) If the bema is the
total raised "east" portion of which the solea extends beyond the iconostas and the ambon juts out from that, then if the solea were large enough, there would be no reason for the ministers to leave the bema/solea/ambon during the liturgy except for an explicit rubric to do so as noted above.
