Russian possessive question

[E. Wayles Browne]

I recently saw an Attestat zrelosti. It contains the line:
Nastojashchij attestat daet ego vladel'cu pravo postuplenija v vysshie
uchebnye zavedenija Sojuza SSR.
And the same thing in Ukrainian, since this was from the Ukr. SSR:
Cej atestat daje joho vlasnykovi pravo vstupu v vyshchi uchbovi zaklady
Sojuzu RSR.
Can someone tell me why it is "ego vladel'cu/joho vlasnykovi" and not
"svoemu vladel'cu/svojemu vlasnykovi"?
