While this "interference" may not be the norm for OEM centerstands, it is not uncommon in the realm of aftermarket centerstands. From the bikes that I've owned, which didn't come OEM with a centerdstand, I have been well aware of this potential on the ones that were affected (Versys & KLR650).
To make the centerstand base more narrow (to prevent said interference) would decrease stability while on the c-stand and also potentially make it more awkward for the operator to reach the centerstand base with their toe while engaging the stand and preparing for lift. My SV650 was this way, meaning that it had a narrow base. It was a challenege to engage the c-stand, to apply pressure to keep the c-stand in contact with the ground, and to awkwardly lift the bike (without tipping side-to-side)in the process.
It sounds as if the key issue is communication. I haven't seen the 2015 installation instructions. It would seem appropriate to include this charecteristic (order of engagement/disengagement) within the installation/operating instructions. If already there, then may be an oversight in catching this step. If not there, it needs to be.
From years of owning/operating aftermarket c-stands (with this charesceristic), I quickly got used to it and it's been a non-issue for me. For me, the conveniences of having the c-stand far outweigh the the slight inconvenience of remembering the prescribed order.
OP- I hope you adjust and do enjoy the use of your stand.
.... The center stand from SW- Motech interferes with the side stand as noted by others. If the side stand is up before raising the center stand, the center stand will not retract fully. .... I received a courtesy call from SW. The caller informed me the review was removed because it contained liability implications. I was also reminded by the SW tech that their site notes the interference may occur between the two stands.
