The sword Weiss summons in Breach is pretty much a shaped projectile that follows the movements of her blade. If you watch, you'll see her directing it towards her enemies. Sure, maybe it's the same sword, but it's not a summon. When Winter used her summoning glyph, she created a beowulf capable of moderate independent movement. That's the difference. What Weiss' summoning is building to is the creation of the giant armor as a familiar capable of its own movement, without relying on constant direction from Weiss.
