Query with respect to Truncating

In the below image, when i use padding and apply truncate from “post” by mentioning maxlen = 5,why don’t the sequence truncate from “post”? It is still applying truncate from “pre”

Can someone please clarify me ??

Please read on the truncate parameter of pad_sequences. The place where truncating happens is specified in the parameter. For instance, if you want to start removing items from start of row, use pre else use post.

Keep in mind that truncation is performed before padding. The default padding is at start of the tokens (i.e. pre)

Here are some examples:
