Box that only has 1 token can't pass an if else statement when the if condition supposed to skip the token check

Question

I have a guardscript that checks 2 tokens to see if its full. However, this can't compile due to the box not have a 2nd token.

val checkTokens: Boolean                 =
    if (SELF.tokens.size < 2) true
    else {
        SELF.tokens(1)._1 == _tokenId.get && SELF.tokens(1)._2 < x
    }

How can we deal with this kind of situation?

This is limitation of v4.x ErgoTree interpreter due to the bugs in AOT costing. Such script should work just fine once v5.0 is activated.
