Supress port script question

[PanzerMike]

There are two events in the _events.txt:

//Axis can't get supplies from Caspian Sea - Expanded by PanzerMike with the small port (1) of Guryev
$SuppressPort
if_Date=1/1/1939
lifespan=continuous
//Baku, Astrakhan, Kransnovdsk
xyArea=223,31,1
xyArea=221,46,1
xyArea=228,33,1
xyArea=226,48,1
$End

//Axis can't get supplies from Caspian Sea - Expanded by PanzerMike with the small port (1) of Guryev
$SuppressPort
if_Date=1/1/1939
lifespan=continuous
//USSR still in the game owning Urals
xyControl=241,75,Allies
//Baku, Astrakhan, Kransnovdsk
xyArea=223,31,1
xyArea=221,46,1
xyArea=228,33,1
xyArea=226,48,1
$End

You can ignore my lines for the port ar 226,48 from my mod.

My question: why 2 events that basically do the same?
