the next verse just after what you posted:
21 The bishop will then lay his hand upon them, invoking, saying,
"Lord God, you who have made these worthy
of the removal of sins through the bath of regeneration,
make them worthy to be filled with your Holy Spirit,
grant to them your grace,
that they might serve you according to your will,
for to you is the glory,
Father and Son
with the Holy Spirit,
in the Holy Church,
now and throughout the ages of the ages.
22 After this he pours the oil into his hand, and laying his hand on each of their heads, says,
"I anoint you with holy oil
in God the Father Almighty,
and Christ Jesus,
and the Holy Spirit."
The second anointing of oil appears to be the Chrismation. The laying on of hands appears to be for the reception of the Holy Spirit. The Chrismation does not appear to be for the reception of the Holy Spirit here.
