Well, it's obvious that the PFA coupled to a force to 3♠ works better in constructive auctions. But the point is a constructive auction is probably not that high a priority after a 3rd seat opener.
This is a philosophical point perhaps worth pursuing separately.
There seem to be two ways of treating 3rd seat openers:
i) 'All bets are off' - all your bidding has to take account of the fact that partner might not have an opening bid, might not have 5 cards in his major. Priority is either to pre-empt, or to confuse.
This school (I assume) takes partner's 3rd seat opening a little more seriously when vulnerable.
ii) Treat them like any other opening bid. Not to absurdity levels (i.e. bear in mind that partner's average minimum is lower than 2nd or 4th seat) but continue to e.g. double a 1NT overcall on a 9 count, invite with a balanced 11-count etc.
I'm happy to admit I'm in this school. When partner opens 1 suit in 3rd seat, even NV, I think he has a normallish opening bid the vast majority of the time, and I don't want to warp my methods to take account of the odd time he doesn't. If he is light on high cards, I expect him to have a good suit and I'm happy raising to the limit.
As a slight side note, if partner has actually psyched (or close to it) then it is often much more effective to treat his call seriously: the opponents get more confused rather than less.
