Does the source champion count as a "nearby ally"?

Certain items have passives that say they affect "nearby allies", but would these passives affect the source champion themselves?

For example, Locket of the Iron Solari has such a unique passive, Legion:

UNIQUE – LEGION: Nearby allied minions and champions gain +15 magic resist (1100 range).

It does not specify whether this passive affects the source champion or not. It could be interpreted that since the source champion is allied and also nearby (in a sense), it does affect them. One could also assume that since it is not explicitly stated, it does not affect them.

So does the source champion count as a "nearby ally", or is it not so?
