According to Makki and Ibn Al`Arabi, it was Ibn Habeeb who made that claim. Makki rejects the claim on the basis that 67:16 is a threat.
While Makki is correct in saying that 67:16 is a threat, that threat can come true. Notice how 54:46 ends with a comparative, "The Hour is more
disastrous and more
bitter"? How did Ibn Habeeb miss that?
Those addressed in 67:16 may be swallowed by the earth AND face a bigger disaster and bitterness on the Day of Judgment. May God save us from that.
If what both verses say can happen, then neither of them abrogates the other.
