I think the commentators of yesteryear sum it up quite well -
You shall not take the name of the Lord, your God, in vain: You shall not swear in vain by the name of the Lord, your God. — [Onkelos] לַֹשָוְא -[This word appears twice in this verse.] (The second [mention of לַֹשָוְא is an expression of falsehood, as the Targum [Onkelos] renders: לְֹשִיקְרָא, as it says [in Shavuos 21a]: "What constitutes a vain oath? If one swears contrary to what is known, [for example, saying] about a stone pillar that it is [made of] gold. (The first [mention of לַֹשָוְא is an expression of vanity, as the Targum [Onkelos] renders: [לְמַגָּנָא].) This [refers to] one who swears for no reason and in vain, [for example making an oath] concerning [a pillar] of wood, [saying] that it is wood, and concerning [a pillar] of stone, [saying] that it is stone. — [from Shevuoth 29a, Mechilta]
