The electrolux/husqvarna/poulan branding thing was a total stuff up from the start. I struggle to think of a worse example.
To start off with (brand wise) Electrolux is the antithesis of Husqvarna. Husqvarna seeks to be a manly "I'm gunna cut me some trees before breakfast" kinda brand. Despite all the other stuff Electrolux sells, Electrolux means vaccuum cleaners in most people's minds. Imagine that you found out that Harley Davidson was owned by Mattel (the makers of Barbie) - would that help make you buy a harley?
On the Husqvarna/Poulan front, rather than having a clear destinction between brands, everyone who is selling Poulan (including the Husky/Poulan regional reps) is yelling "these Poulans are great, they are made by Husqvarna." If they are great, then you've prevented customers from buying a saw at a higher price point. If they aren't great (and trust me, they aren't) then anyone who thinks that Poulan is a POS will think that Husqvarna is too.
Manufacturing the little huskies in the Poulan factory is also a marketting disaster. Having chosen not to buy a Poulan POS and handed over a heap more $$$, the customer discovers that the have really bought a Poulan. The little huskies might be fine saws, but it is a marketting and customer satisfaction disaster.
