All I could think of is the e levelling. cédait /sɛdɛ/, aimer /eme/.
I don't understand what he means by the o's. All au, eau, ô, and o in final open syllable/in closed syllable with /z/ represents /o/ whereas in the rest, it's /ɔ/. Of course you have a few weird cases like os (/ɔs/ = singular, /o/ = plural), Paul, yacht, maximum, etc.
What made it hard for me to figure out is /ɑ/ since dictionaries tend to replace it with /a/ in words that historically have /ɑ/. Euro-centralist dictionaries I may add because I prefer to speak the Canadian way.

The three-consonant rule: CəC vs CəCC/CCəC
je viens /ʒə vjɛ̃/ vs le travail /lə tʀavaj/
samedi /samədi/ vs gouvernement /guvɛʀnəmɑ̃/

il ne te le demandera pas. /il tə lə dəmɑ̃dəʀa pɑ/
