Cam plate oil hole for timing chain?

It confused me because the manual I have is an original manual from chrysler! It is red white and blue in color on front cover and is for 1975 chrysler chassis/engine. It shows a clear pic of bolt with hole on drivers side. However, I see how it makes more sense to put bolt with hole on left (looking @ motor from front side.) Since oil will come down to oil slinger tab as a direct or more direct shot than other side.
