If we include the preceding two words of that (nested) quote, we see additional beings implied…
- For you there is precisely one being in samsara and that’s you
- For me there is precisely one being in samsara and that’s me
- For Seth Meyers there is precisely one being in samsara and that’s Seth Meyers
- For x there is precisely one being in samsara and that’s x
That’s not looking like solipsism. I took it to mean something like “whether the number of beings be finite or infinite, one* can only ever experience it from one’s own p.o.v.”
