Well, allow me to simplify this with another story that happened to a close friend of mine.
Her son was ready for a shidduch and they red her something very suitable. The problem was, that the girl’s father had the same name as her son.
They wanted to ask their regular Rav who happend to have been in the hospital at the time and was not avaialble due to an illness. So they asked soemone else who said its ok, but they must ask 2 other Rabbonim (yochid bzerabim, halacha kirabim). The other 2 approved it as well. The shidduch was made.
After their regumar Rav was released from the hospital,they found out that HE is VERY MAKPID NOT TO TAKE THE SAME NAME.
Had he not been ill as the time, they would have asked him and not gone through with the shidduch because he would have opposed it.
One might ask, had they waited for him to be released from the hospital (it wasnt a serious illnes) they might have found something more suitable.
THIS WAS HIS ZIVUG. Hakodosh B’ Hu rules the world!!
