If I asked you for an answer to a math question, then you showed me the answer with how you got there, on a very quick glance I might say: "That appears to be correct."
It could mean they've seen more evidence to make that assessment, or are basing that assessment on the same evidence we have. Regardless, "appears to be" is hedging in the absence of certainty.
> Bundesverteidigungsminister Boris Pistorius vermutet im Fall von zwei in der Ostsee beschädigten Kabeln zur Datenübertragung eine vorsätzliche Aktion durch Dritte. Man müsse davon ausgehen, dass es sich um Sabotage handle, sagte er am Rande eines Treffens mit seinen EU-Amtskollegen in Brüssel. Beweise dafür gebe es bislang aber nicht. Er betonte: "Niemand glaubt, dass diese Kabel aus Versehen durchtrennt worden sind."
> Federal Minister of Defense Boris Pistorius assumes the case of to damaged baltic sea data cables to be the intentional action of a third party. One should assume it to be sabotage, he said while at a meeting with EU colleagues in Brusseles. Proof, however, is not available yet. He emphasized: "Nobody believes that those cables were cut by accident."
So while carefully not saying anything definitive and firm, he very strongly hints in the direction of sabotage.
On the other he is framing a conspiracy theory: "Something happened that appears to be sabotage and sabotage would be done by the enemy. " and the European media has been stuffed full of conspiracy theories during the entire conflicts.
Educationally you can look at the Nord Stream pipelines sabotage.
Nearly every EU and US source writes in big letters that Russia was behind it. After a while, it became nearly impossible to keep that conspiracy theory alive.
Sweden and Denmark ended their investigation into the matter with no conclusion drawn The present narrative is that the sabotage was done by a Ukrainian team with a shoe string budget:

In this case, this is a government official speaking to the press (i.e. in an official capacity). If they were to say "this was sabotage," that is a definite declaration that the government believes - again, officially and on the record - that an outside party has deliberately done material damage to their country. Given the general situation, it is not a huge leap to come to the interpretation that "this was an attack against our country, and possibly an act of war."
No government official would want to be within miles (or kilometers) of that sort of statement unless they have pretty much already internally decided from the top-down to escalate the situation. Almost no single government agent has the authority to escalate the situation in that manner. So what we end up with is "appears to be." This overtly says 'all available evidence points to this being the case, however something else cannot be ruled out.' (As a sibling comment suggests, it can also act as a type of propaganda). So it is not an official government declaration that another nation has damaged them, but they have reasons (probably both apparent and not) to believe what they are saying publicly.
What the latter actually said was much stronger and less ambiguous.
