Does using 2 weapons have the same restriction with fighting through with supporting spears/pikes, as fighting with a 2-handed weapon?

(Such as with the Elf Twins and their Twin Elf Blades?)

No only men with a 2 handed weapon may not have spear support.

PS: The special rule of the twins say you may use 2 blades ore 1 blade as a 2 handed weapon.
