Yes, I checked it using binary output of version 1.4.4 without the dissector
changes.

the packets are generated using the following code

xr->rb[0].blockheader2            = (uint32_t) session->rcv.pt;
xr->rb[0].msci                = htonl(client.msci);
xr->rb[0].source_ssrc            = htonl((uint32_t) rcv.ssrc);
xr->rb[0].ntp_ts_pkt_rcv_msw    = htonl(xr_sc.ntp_rcv_ts_msw);
xr->rb[0].ntp_ts_pkt_rcv_lsw    = htonl(xr_sc.ntp_rcv_ts_lsw);
xr->rb[0].rtp_ts_pkt_rcv        = htonl(rtp_pkt_ts);
xr->rb[0].ntp_ts_pkt_presented     = htonl(xr_sc.short_ntp_presentation_ts);


The field order is :

typedef struct xr_sync_block
{
        uint32_t blockheader1;
        uint32_t blockheader2;
        uint32_t msci;
        uint32_t source_ssrc;
        uint32_t ntp_ts_pkt_rcv_msw;
        uint32_t ntp_ts_pkt_rcv_lsw;
        uint32_t rtp_ts_pkt_rcv;
        uint32_t ntp_ts_pkt_presented;
} xr_sync_block_t;
