Blessings over Wine at the Passover Seder

And one drinks the second cup. Rav Alfas wrote that one needs to bless "Creator of the fruit of the vine". And similarly has Rav Natronai, Rav Amram, and Maimonides written. But my father, Rabbi Asher ben Yehiel (1259 – 1327) wrote that one only needs to bless "Creator of the fruit of the vine" upon the first cup over kiddush and upon the third cup over the grace after meals. And similarly has Rav Kohen Tzedek.
Regarding the post-consumption blessing, Rav Alfas wrote that one needs to bless following the second and fourth cups. But his words were questioned as to why bless after the second cup?

Even though the rabbis established the four cups each as a mitzvah unto themselves, nevertheless, since it has not departed from one's mind from drinking, since one blessed upon the first cup and knew they were going to continue to drink another cup. Therefore, one need not bless upon each and every cup.

If they brought another wine, one does not bless "Creator of fruit of the vine", but one blesses "The Good and The One Makes Good" upon it.
Rabbi Isserles: Even though there is no more left from the first cup.
It is not necessarily that they just now brought another wine, rather this is the case if these two wines were present at the outset, then one blesses "The Good and The One Makes Good" upon it.
Rabbi Isserles: And specifically when they were not set out in front of the person together when they blessed "Creator of fruit of the vine", but if they were set out in front of the person at the outset, then one need not bless, except "Creator of the fruit of the vine".

Rabbi Yaakov ben Moshe Levi Moelin (1365-1427) wrote, "There are those who say to not bless 'The Good and The One Who Makes Good' on the night of Passover in order to not have a lot of cups of wine." But it seems to me that one should not drink from two different types of wine. But if they brought a different type of wine to that person, one needs to bless, since it is explicitly mentioned in the Talmud. And see §472:1 in the Set Table and the Tur there.
Rabbi Alexander Suslin HaKohen (early 14th century) wrote that this is a superfluous stringency. And similarly has Rabbi David Abudarham (14th century) written, quoting Rabbi Meir of Rothenburg (1215-1293). And similarly did Rabbi Jacob ben Asher (1270-1340) write in his Tur §473 that one should bless.

It seems to me that one should bless "Creator of the fruit of the vine" upon a different wine since one does not need to bless "The Good and the One Who Makes Good" since we are already saying "The Good and the One Who Makes Good" in the grace after meals.

It is explained in §472 that it is permissible to drink as much as one would like between cups however much they would like to do if one does not need to bless "Creator of the fruit of the vine", but any cups of wine that requires a blessing seems as if one adds on to the cups. But when one needs to bless "The Good and The One Who Makes Good" seems as if one is adding to the cups.
