It's not a matter of whether it retracts or not, it's what it looks like
after it's retracted. Instead of being seen to extend up into the body like it should, it looks like something that is simply attached to the bottom as a separate piece (even if it really isn't).
I suppose it's not the most important thing ever, but it's a cool little detail that I've always loved about the physical prop, and I'm really bummed not to see it on the SSC version.
Although looking at the pics again, I suppose it's possible the guy taking these pics simply pulled the leg out a lot farther than it should have been, in which case.... never mind.
