1) We learn from the ืืฉื ื ืืจืืจื that the ืืจืืืช of ืงืจืืืช ืฉืืข are not ืืขืงื to fulfilling your ืืืื of ืงืจืืืช ืฉืืข. So you can technically fulfill the ืืฆืื of ืงืจืืืช ืฉืืข without saying the ืืจืืืช of ืงืจืืืช ืฉืืข ๐ซก๐โผ๏ธ
2) This is practical for example when it comes ืฉืืช morning and ืกืืฃ ืืื ืงืจืืืช ืฉืืข is at 8:30, and your ืื ืื is also at 8:30, meaning youโd need to say ืฉืืข before davening. So in this case, itโs practical that the ืืจืืืช arenโt ืืขืงื to your fulfillment of ืงืจืืืช ืฉืืข, and what youโd do is say ืฉืืข alone without the ืืจืืืช, in order to fulfill ืงืจืืืช ืฉืืข ืืืื ื๐๐จ๐ปโณ
3) So what happens when the ืื ืื gets up to ืงืจืืืช ืฉืืข (after the ืืื had already passed)? Youโd say the ืืจืืืช as normal and fulfill your ืืืื of ืืจืืืช ืงืจืืืช ืฉืืข, and then say ืฉืืข with the ืฆืืืืจ, because after all ืฉืืข is ืชืืจื, and thereโs nothing wrong with just reading some ืชืืจื โผ๏ธ๐
