no, what happened is the following
Pika thinks "everyone is here. I will post this."
He then types the first part of his message.
However he then thinks "wait, what if the full cast is not actually here?"
So he places his eye cursor on the leftmost figure and begins to verify one by one left to right that each member of the cast is there.
But he wants to save his memory since he has a lot of other things on his mind, so he decides that he'll forget each character's name after he recognizes it, and instead just remember how many of the cast members appeared.
When his eye seeks to the end and verifies the last character, he knows that the whole cast is there because the number he counted is the same as the cast size.
But there's a problem... Because he didn't remember the names of each one, he doesn't know what to write in the message!
He thinks "I COULD return my eye cursor to the beginning, and then go from left to right and write the name of each character. BUT, then I would end up moving twice the amount..."
He realizes that in order to best preserve the number of uses of his eyes, which can only traverse a fixed number of degrees in their lifetime, it's more efficient to instead write the name of the characters in reverse order starting from his current position at the right.
