Experts state that the arterial sheet should be removed first on these two webpages within the Cath Lab Digest website.

Following is a section in a cardiac cath book that also states that the arterial sheath should be removed first. The citation for the book and a link to access it follows the quote. The path to click to get to the particular passage in the book is also included after the quote.
“Control of the Puncture Site Following Sheath Removal
Originally, standard groin management required the effect of heparin to wear off or be reversed by protamine to an ACT <160 seconds before the arterial catheter and sheath were removed and manual pressure applied, except in the case of bivalirudin as mentioned above. Manual pressure method is best applied using three fingers of the left hand that are positioned sequentially up the femoral artery beginning at the skin puncture. With the fingers in this position, there should be no ongoing bleeding into the soft tissues or through the skin puncture, and it should be possible to apply sufficient pressure to obliterate the pedal pulses and then release just enough pressure to allow them to barely return. Pressure is then gradually reduced over the next 10 to 15 minutes, at the end of which time pressure is removed completely. The venous sheath is usually removed 5 minutes after compression of the arterial puncture has begun, with gentle pressure applied over the venous puncture using the right hand. To avoid tying up the catheterization laboratory during this period, patients were usually taken to a special holding room in the catheterization laboratory or back to their hospital beds before the sheaths were removed. If such relocation is to be performed prior to sheath removal, it is important that the sheaths are secured in place (suture, or at least tape) to prevent them being pulled out during transport.
When procedures are performed using larger arterial sheaths or with thrombolytic agents or IIb/IIIa receptor blockers, more prolonged (30- to 45-min) compression is typically required. To avoid fatigue of the operator or other laboratory personnel performing compression, occasionally a mechanical device (Compressar [Applied Vascular Dynamics, Portland, OR], The Clamp Ease device [Pressure Products Inc., Rancho Palos Verdes, California] or FemoStop [Radi Medical, Wilmington, MA]) can be used to apply similar local pressure. These devices can be equally or even more effective in prolonged holds,22 but are uncomfortable for the patients and human supervision is required while in place; hence manual compression is preferred for removal of smaller (6F) sheaths or in patients with peripheral vascular disease or prior peripheral grafting surgery where occlusive compression or flow restriction might cause arterial occlusion. In every case, however, it should be emphasized that a trained person must be in attendance throughout the compression to ensure that the device is providing adequate control of puncture site bleeding and is not compromising distal perfusion.”
