I don't know where these people are coming from or why they are saying what they are, but if they are Catholics, they are dissenting from the Church.
Don't listen to them. This is what the Catechism of the Catholic Church says is the proper form or words that should be used in administrating the Sacrament of Baptism:
The mystagogy of the celebration
1240 In the Latin Church this triple infusion is accompanied by the minister's words:
"(<First> Name), I baptize you in the name of the Father, and of the Son, and of the Holy Spirit."
In the Eastern liturgies the catechumen turns toward the East and the priest says:
"The servant of God, (<First> Name), is baptized in the name of the Father, and of the Son, and of the Holy Spirit."
At the invocation of each person of the Most Holy Trinity, the priest immerses the candidate in the water and raises him up again.
This has always been the proper form for Baptism; there was no change.
