What many people fail to understand is that extension and expansion of limbs occur during the molting process, while the limbs are being pulled out of the old skin. The limbs already start to harden during this phase, but they do not reach 100% durability. After the limbs have been pulled out, the amblypygid folds them immediately under its body, while still being attached to the old skin by the tip of the abdomen. So it does not need to spread its legs apart. Even the antenniform legs do not need as much space to spread as most people would think. Once the legs reach a certain degree of hardness, the amblypygi places them on the molting surface (holding itself up side down or vertically) and rests while its body hardens. So another possible scenario to what happened is that at some point the animal lost grip on the cork or the old skin and moved to the ground level. While being there, it had to support its body weight above ground, which can cause the walking legs to curve. This is not a handicap by any means. The animal will still behave normally and feed.
