Has another tool called xdpdump. It was built around ebpf as well, specifically:

xdpdump to capture the original packet at ingress and the modifications the XDP program has made to the packet after execution

Is this the same for xdpcap?

Unfortunately not, currently xdpcap only supports capturing the packet after the program has run. #51 tracks adding support for this.
