yes it's his npub. ots is simply a cryographic approach to proof something happened after a specific time. for example when an event published. someone did an ots for ross post and @npub1ej49...ndrm is wondering is that him or someone else. afaik, ross is using primal and primal won't let him to do it. so, i believe its someone else probably using amey. not hard to find out who is him. i hope it be clear for you.

As an additional remark: its actually based on the Bitcoin blockchain. You can now cryptographically proof that the timestamp i produced, is (in special way) embedded in a particular bitcoin block. This means that any outsider (that has his hands on this proof) can verify that Ross his post must have existed before the time of that particular Bitcoin block. And because of Bitcoin's proof of work system, you have high assurances as to when (roughly) that must have been. Unfortunatly you don't know how long before, but at the very least not after. Now because its just a proof and it relies on Bitcoin, it does not matter that I was the one that produced the proof, i am completely irrelevant to the verification process. I.e anyone can timestamp anything from anyone else.
