The only reason this matters, is to put more pressure on those countries. After the invitation the next step is the all members must sign the Accession Protocol, which when all have signed would make Ukraine a member. Since those seven countries do not want Ukraine to become a NATO member right now, since that would mean war with Russia, they do not agree on sending the invitation to not be insulted by Ukraine all day long for not ratifying the Accession Protocol. This way it is all rumors and I gurantee you there are more then seven NATO members not wanting a war with Russia.

Really common sense and to be expected right now.
