I have two questions for (1).

(1) He is not so busy that he can’t go for a walk now and then.

#1
Do you agree that (2) is the paraphrase of (1)?

(2) He is not too busy to go for a walk now and then.

#2
Do you agree that (3) correctly explains what (1) actually means?

(3) Though he is (very) busy, he can still go for a walk now and then.

Thank you in advance
