I belive you are wrong, they are clear, and the wizard is limted by his slots, and the slots of the multi class table trump the wizard table...
so one of your two statements is false at least, it is either not clear, or I am not wrong... if you think A is correct and I think B is correct it can not be clear because we both read the same thing differently... I play in 2 regular groups (with a bit of overlap) so I am regularly in contact with 7 people who play, 6 of them own PHBs... (plus me so 8 total 7 own PHBs when you add me) we all read it the same way... One of those regulars works at my FLGS (and comic book shop) and he has had this discussion before, with others at the store... I am yet to hear anyone claim it is BOTH clear and that EVERYONE I KNOW IS READING THE CLEAR STATEMENT WRONG, although to be fear were we think it is clear and we are correct, some people do think it is badly worded and we are reading it wrong...
My apologies, I accept that it's not clear to you and your group. I just don't understand why, because it seems quite clear to me.
Did you look at the text I cited on PHB pg 164? It specifically uses a multiclass wizard as the example. He is a Ranger 4/Wizard 3, meaning he is a 5th level caster (and has 3rd level spell slots). However, it specifically explains that he only has access to the spells that would be available to a 3rd level wizard, rather than a 5th level wizard.
This is perfectly in line with the multiclass spellcasting rule, "You determine what spells you know and can prepare for each class individually, as if you were a single classed member of that class". A 3rd level wizard can normally only cast 2nd level spells, so it follows that a multiclassed 3rd level wizard would only be able to prepare up to 2nd level spells, even if he has access to higher spell slots.
