Not moot at all. It’s a contemporary report of a bullet being in Connally’s leg.
A report based on what, exactly?
This is how Shaw describes the wound in Connally's thigh when he first saw it:
Mr. SPECTER - You have described, in a general way, the chest wound. What other wounds, if any, was Governor Connally suffering from at the time you saw him?
Dr. SHAW - I will describe then the wound of the wrist which was obvious. He had a wound of the lower right forearm that I did not accurately examine because I had already talked to Dr. Gregory while I was scrubbing for the operation, told him that this wound would need his attention as soon as we were able to get the chest in a satisfactory condition. There was also, I was told, I didn't see the wound, on the thigh, I was told that there was a small wound on the thigh which I saw later.
[...]
Mr. SPECTER - Dr. Shaw, what wounds, if any, did the Governor sustain on his left thigh?
Dr. SHAW - He sustained a small puncture-type wound on the medial aspect of the left thigh.
Mr. SPECTER - Did you have an opportunity to examine that closely?
Dr. SHAW - No.
Mr. SPECTER - Did you have an opportunity to examine it sufficiently to ascertain its location on the left thigh?
Dr. SHAW - No; I didn't examine it that closely, except for its general location.
[...]
Mr. SPECTER - With respect to the wound you described on the thigh, Dr. Shaw, was there any point of exit as to that wound?
Dr. SHAW - No.
Mr. SPECTER - I now show you----
Mr. DULLES - Could I ask one more question there, how deep was the wound of entry, could you tell at all?
Dr. SHAW - Mr. Dulles, I didn't examine the wound of the thigh so I can't testify as to that. Dr. Gregory, I think, was there at the time that the debris was carried out and he may have more knowledge than I have.
Shaw did not treat the wound. Shaw never even claimed that he really examined the wound. Nor did he ever claim to have seen an x-ray showing a bullet in the thigh. For that matter, no one else claimed that a bullet was found in the wound, or that bullet could be seen in the x-rays taken of the Governor's thigh.
From his own testimony, all Shaw would have known at the time was that there was one, and only one, wound in the thigh. It's no stretch to think that Shaw concluded that a projectile had entered the thigh through the wound and remained in the leg, based on what little he knew. But he knew little about it, as he admitted.
You can choose to believe the physician who treated the wound and the x-rays created to facilitate this treatment, or you can choose to believe something said by another doctor who'd left the OR while the thigh surgery was being performed. A doctor who admitted that he "didn't examine [the thing wound] that closely, except for its general location." This shouldn't be a difficult choice.
