Section 5.6.2.1.4 of SP 800-56A rev. 3 (page 36) states that the owner of a static ECC key pair (d, Q) shall compute dG and compare it with Q prior to using the key. Softoken performs some group operations (not exactly these ones, see sftk_PairwiseConsistencyCheck) for all ECC key pairs, both static and ephemeral.
We should save some effort in TLS handshakes by defining a PKCS#11 mechanism for ephemeral key pairs that avoids the pairwise consistency check.
